FCC Regulatory Compliance

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

This equipment has been tested and found to comply with the limits for a Class A digital device pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manuals, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.

Modifications to this product not expressly approved by Proxim, Inc., could void the FCC approval and the user's right to operate the product.

The Stratum is intended for point-to-point operations over an unobstructed line-of-sight path.

This equipment is authorized for use by the FCC, under the United States Code of Federal Regulations Title 47 Part 15 Subpart E – Unlicensed National Information Infrastructure Devices (UNII).

To comply with FCC rules for UNII devices:

1. The equipment must be installed in accordance with CFR 47 Section 15.407 (a) (3) which states: “The operator of the U-NII device, or if the equipment is professionally installed, the installer, is responsible for ensuring that systems employing high gain directional antennas are used exclusively for fixed, point-to-point operations.”

2. The installer must ensure that the unit is properly installed in compliance with the FCC’s guidelines for maximum permissible radio frequency exposure as outlined in CFR 47 Section 1.1307(b)(1), preventing excess exposure to all persons. The installed radiating device should be inaccessible to unauthorized personnel. The installed unit should be positioned to guarantee no direct continuous exposure to people within 5 feet of the antenna. During installation, the installer should use caution to avoid excess exposure to directed antenna radiation within 3 feet of the front of the antenna.

3. The unit is normally provided with an integral flat panel antenna for both the “A” end (5.3 GHz transmitter) and the “B” end (5.775 GHz transmitter) of the point-to-point link. For extended range applications, the unit at the “B” end may be provided with a connection for an external parabolic antenna instead of an integral flat panel antenna. When deployed with an external antenna, the unit must be professionally installed to comply with CFR 47 Section 15.203. Only antennas with gain less than 40 dBi are authorized for use with the “B” unit. The antenna gain improvement at the “B” end of the link aids both directions of the link.

Industry Canada Regulatory Compliance This device complies with Industry Canada specification RSS-210 for “Low Power License-Exempt Radio Communication Devices,” Section 6.2.2 (o1), “Local Area Network Devices.”

The Stratum is designed for point-to-point communications and operates within the bands 5250-5350 MHz and 5725-5825 MHz.

Users should take note that high power radars are allocated as primary users (meaning they have priority) of 5250-5350 MHz and 5650-5850 MHz and these radars could cause interference and/or damage to LELAN devices.

Users should also take note of the maximum antenna gain permitted to comply with restrictions for those bands:

5250-5350 MHz

“The maximum transmitter power shall not exceed 250 mW or 11 + 10 Log B dBm, whichever power is less. The power spectral density shall not exceed 11 dBm in any 1.0 MHz band. The maximum EIRP shall not exceed 1.0 watt or 17 + 10 Log B dBm, whichever power is less. B is the 99% power bandwidth in MHz.”

The Stratum ODU-A transmits between 5250-5350 MHz. The transmit power is +1 dBm. The integral flat panel antenna gain is 26 dBi. The EIRP is 27 dBm and complies with the requirement above.

5725-5825 MHz

“Fixed point-to-point devices for this band are permitted up to 200 watts EIRP by employing higher gain antennas, but not higher transmitter output powers. Point-to-multipoint systems, omni-directional applications and multiple co-located transmitters transmitting the same information are prohibited under this high EIRP category.”

The Stratum ODU-B transmits between 5725-5825 MHz. The transmit power is +1 dBm. The integral flat panel antenna gain is 26 dBi. The EIRP is 27 dBm and complies with the requirement above.

The Stratum ODU-B-EXT transmits between 5725-5825 MHz. The transmit power is +1 dBm. External parabolic antennas with gain up to 52 dBi will comply with the requirement above.

Safety Warning

Before aiming the antenna or working near the antenna, read this entire manual and follow the instructions carefully.

DO NOT STAND IN FRONT OF THE ANTENNA WHILE POWER IS ON.

Be sure to provide adequate grounding and lightning protection. Do not install the Outdoor Unit near overhead electrical wires.

This unit is intended for point-to-point operation over an unobstructed line-of-sight path. It is the responsibility of the installer to ensure the unit is properly installed in compliance with the FCC’s guidelines for maximum permissible radio frequency exposure outlined in CFR 47 Section 1.1307(b)(1), preventing excess exposure to all persons. The installed radiating device should be inaccessible to unauthorized personnel. The installed unit should be positioned to guarantee no direct continuous exposure to people within 5 feet of the antenna. During installation use caution to avoid excess exposures to directed antenna radiation within 3 feet of the front of the antenna.

The transmit power output from the Stratum is less than 0.8 milliwatts. However, after the gain of the standard 18-inch flat panel antenna is added, the Effective Radiated Power is approximately 0.5 watts. Microwave radiation can cause tissue heating, potentially affecting the eyes, and causing permanent damage to vision.

Stratum Installation and Maintenance Guide •••• 7

Chapter 1: Introduction

The Stratum is a wireless Ethernet bridge designed to deliver dedicated full duplex 20 Mbps or 100 Mbps connectivity with fiber reliability. The Stratum transports all Ethernet traffic types in addition to two T1 channels.

With full duplex Ethernet bridging and two T1 links for applications such as voice traffic, Stratum satisfies many short haul, high capacity communications needs.

In contrast to millimeter wave equipment, Stratum delivers high throughput with none of the negative factors associated with millimeter waves. There’s no worry about rain fades or poor bit error rates. Stratum links perform as well as fiber, at a fraction of the cost and with far less time to deploy.

Features • Full duplex 20 Mbps or 100 Mbps LAN bridging

• Dual T1 transport for TDM voice and data traffic without impact to LAN performance

• Unlicensed U-NII band operation allows fast deployment and is immune to weather fades

• Fiber class performance

• Fully SNMP managed using industry standard platforms such as HP OpenView

Product Overview Proxim’s Stratum is the first product operating in the U-NII bands to merge high capacity voice and data with ease of installation and operation. Stratum incorporates a MAC layer Ethernet bridge for high capacity bridging of all Ethernet traffic types, including IP and Voice-over-IP. With auto-negotiation for 10/100 Ethernet, full or half duplex LAN support combined with 802.1d Spanning Tree functionality, Stratum requires very little in the way of initial configuration. In addition to the 20 Mbps or 100 Mbps full duplex bridging capabilities, Stratum includes two DSX-1 interfaces for transport of voice between digital PBXs or other T1 traffic. The DSX-1 interfaces operate equally well for channelized or unchannelized T1 applications.

Operating at distances of up to 7 miles, Stratum far outperforms ISM band radios and Infrared devices. Also, Stratum is easily managed using SNMP or the native HTML Graphical User Interface.

Chapter 1: Introduction •••• 8 Stratum Installation and Maintenance Guide

Rapid Deployment Stratum operates in the newly allocated U-NII bands, with no FCC licensing requirements. Unlicensed band operation removes the waiting time involved with frequency coordination and license approval. Stratum can be deployed immediately in contrast with up to six weeks delay for deployment of licensed band products. Additionally, if you need to move the link, the Stratum antennas may be relocated without applying for license changes.

Fiber Class Performance For years, fiber has been the performance standard for communications media. Today, Proxim brings the outstanding performance of fiber to wireless communications. Stratum employs a concatenated Reed-Solomon (t=16) Forward Error Correction and Viterbi convolutional decoding to provide the highest degree of error correction, which is transparent to the user. Because Stratum operates in the 5 GHz U-NII bands, rain, fog and other weather conditions do not adversely affect operation.

100 + 3 Mbps or 20 + 3 Mbps Full Duplex Throughput The Stratum 100 delivers 100 Mbps full duplex throughput for transport of Ethernet traffic, so the wireless link is no longer a bottleneck on the network. The Stratum 20 provides all of the features of the Stratum 100 but delivers 20 Mbps full duplex throughput and is ideal for applications requiring less bandwidth.

In addition to the 100 Mbps or 20 Mbps wireless connectivity available for LAN traffic, Stratum incorporates two DSX-1 interfaces for point-to-point transport of T1 traffic, such as digital voice. Each T1 operates at full speed and does not share bandwidth with the LAN traffic; so all data streams receive the maximum throughput with the lowest latency. Stratum’s broadband capabilities make it the ideal choice for bandwidth hungry applications like multi-Megabit Internet access, Voice-over-IP, and real-time video and imaging.

Installation, Maintenance, Management, and Monitoring Designed for installation and maintenance by IT professionals, one or two qualified individuals can install a Stratum link in a matter of hours. The Stratum’s “Aiming LED” allows the installer to aim the antennas without using costly test equipment.

Stratum requires no maintenance or calibration for the life of the product. Software upgrades to the Outdoor Unit are downloaded from the Indoor Unit via the IDU-ODU fiber interface.

SNMP or TELNET allow easy day-to-day monitoring, and you may manage the Stratum from any standard SNMP manager such as OpenView or SunNet Manager™. The Industry standard MIB II and a Proxim Enterprise MIB allow full access to parameters for SNMP management. Stratum can send traps to multiple hosts on networks where management is distributed among more than one computer.

An integrated menu-driven configuration and management tool allows the operator to review the system parameters at a glance and to access packet and radio statistics for both ends of the link from a single interface. An integrated HTML interface is also standard and allows password protection to prevent unauthorized access.

Stratum Installation and Maintenance Guide Chapter 1: Introduction •••• 9

Standard Configuration The Stratum consists of three units:

• The Indoor Unit (IDU) is a rack-mountable unit that contains the electronic bridging components. The IDU can be installed in any convenient climate-controlled location within a building. The IDU must be powered from an 110V or 220V AC source.

• The Outdoor Unit (ODU) is a pole-mountable weather tight unit which contains the RF components and includes an 18" x 18" x ¾" flat panel antenna. An ODU-A transmits in the mid-UNII band, centered at 5287 MHz. An ODU-B transmits in the upper-UNII band centered at 5782 MHz. One ODU-A and one ODU-B are required for a Stratum link.

• The Alignment Mounting Bracket (AMB) is a galvanized steel bracket used to mount the ODU to a pole of 1.9 to 3.5 inch diameter. The AMB can be adjusted on the pole in both vertical and horizontal axes to align the flat panel antenna along the line-of-sight path.

The IDU and ODU must be interconnected via two multi-mode fiber cables, one for transmit, one for receive. A shielded two-conductor cable (with drain) is required to supply DC power from the IDU to the ODU. The IDU will supply adequate DC power over a 1000-foot span to the ODU using 18 AWG wire pair.

Figure 1 shows a typical link bridging network traffic between two buildings. The two ODUs in the diagram are mounted on the roofs of two adjacent buildings and the associated IDUs are located inside these buildings.

Sample Stratum Installation

The standard Stratum link is supplied with a pair of high-performance, flat panel phased-array antennas to establish a connection over a distance of up to 4 miles. The small antenna size (18"x18"x3/4") and light-weight outdoor unit allow building-top installations to use a cost effective tripod or parapet-braced pole mount. Alternatively, a Stratum link can establish a connection over a distance of up to 7 miles using a high-gain parabolic antenna at one end.

Optional External Antenna Configurations For extended range applications, the ODU at the “B” end of the Stratum link may be supplied with an “N” connector for an external parabolic antenna instead of the integral flat panel antenna. The ODU-B-EXT allows the Stratum to utilize industry standard parabolic antennas. Parabolic antennas are commercially available in 2, 4, and 6-foot diameters that are characterized for both the mid and upper U-NII frequency bands. Use of such antennas can increase overall link system gain to achieve connectivity over a distance of up to 7 miles with 99.99% Availability.

Chapter 2: Installation •••• 10 Stratum Installation and Maintenance Guide

Chapter 2: Installation

Installation Preparation: The Path Survey & Cable Installation Before beginning installation, you should complete path and site surveys for the link, including line-of-sight path planning, antenna supports, and pre-installation preparation. The path survey should also specify the expected signal strength between the two antennas. Proxim strongly recommends that a qualified radio engineer perform the path survey. The procedure to perform a path survey is beyond the scope of this manual. If you have questions about or problems with the path survey, contact your reseller or Proxim Technical Support.

Assembling Tools and Cables Before You Begin The following tools are needed during installation:

For Installing the IDUs and ODUs • 1/2" socket wrench

• 1/8" slotted screwdriver

• Assorted hand tools

• #2 Phillips screwdriver

• Digital multi-meter

• Torque wrench (if you intend to change antenna polarity)

• PC or laptop running HyperTerminal, or an equivalent VT-100 terminal emulation program. The PC or laptop must have a serial port with a DB-9 male connector or adapter to connect to the serial cable’s DB-9 female connector.

• Straight through 8-pin RJ-45 serial cable

Stratum Installation and Maintenance Guide Chapter 2: Installation •••• 11

For the Cabling Between Each IDU and the Associated ODU • 62.5/125 µ fiber, multi-mode 850 nm cable (for data transmission); the subunit diameter (outer diameter of

the fiber) should be 2.7 to 3 mm. Two fibers are required for each IDU-ODU pair. See step 2 for cable specifications.

• Fiber inspection scope

• Multi-mode fiber light loss test set

• ST termination kit

• Fiber cleaning materials

• Shielded 2-conductor 18-gauge AWG cable with drain wire (for DC power connection)


Step 1. Installing and Mounting the ODUs The following instructions describe how to assemble and mount a single ODU with integrated flat panel antenna. Refer to the end of this section for information on how to mount the ODU-B-EXT using a parabolic antenna.

Remove the ODU, pre-assembled Antenna Mount, and Accessory Kit from their shipping cartons. Save all packing materials in case you need them later.

Using the foam packing material to protect the painted surfaces of the antenna, carefully place the ODU on the packing foam with the antenna facing down.

Set aside the accessory kit. Use this hardware to attach the antenna mount to the ODU, and to attach the complete ODU to a supporting mast.

Note: The ODU and antenna are factory weather-sealed. DO NOT DISASSEMBLE THE ODU OR REMOVE THE ANTENNA – THIS WILL VOID THE WARRANTY.

The ODU’s connectors are shown in Figure 2 below.

Setting Antenna Polarization Antenna polarization must be the same at both ends of each link. For single links, vertical polarization is a good default. For multiple links located on the same rooftop, alternating the antenna polarization of independent links is recommended. Contact your Proxim Systems Engineer if you are interested in using more than one pair of Stratum units in a multiple link solution. There is no performance difference between vertical and horizontal polarization.

The Stratum units are shipped from the factory with vertical polarity (cable connectors facing down). Note that for vertical polarity, the company logo appears in the top left corner of the unit, when viewed from the front.

To change to horizontal polarity, follow the steps below:

The following steps should be done in a clean setting to avoid getting any particles into the heat seal.

1. Remove the 4 bolts holding the sunscreen and remove the sunscreen.

2. Remove the 4 spacers, 4 nuts, and lockwashers holding the heat sink in place.

3. Rotate the heat fin clockwise 90°.

4. Replace the spacers, lockwashers, and nuts for the heat sink (tighten to 24 inch-pounds using a torque wrench).

5. Reattach the sunscreen.

The nuts, bolts, and spacers must be tightened to 24 inch-pounds to ensure adequate heat transfer and avoid damage to the radio housing.

Note that when using horizontal polarity, the connectors are on the left and the company logo appears on the top right of the unit, when viewed from the front.

Attaching the Antenna Mount 1. Slightly loosen the six 5/16"-18 bolts on the Antenna Mount’s slotted elevation arms and angle brackets

(three on each side) so that they can be positioned for the next step.

2. Attach the Alignment Mounting Bracket to the ODU Angle Brackets. Do not tighten all the way: you will need to adjust the position of the Antenna Mount at a later point in the installation process.

Note: Avoid scratching the painted surfaces of the ODU during the installation of the antenna mount.

Antenna Mast Requirements The ODU must be mounted on a tubular steel mast (1.9 to 3.5 inches outside diameter) using the remaining hardware supplied in the antenna mount accessory kit. The mast must be stable, not able to bend or rotate under extreme weather conditions, and must provide a line-of-sight path to the other end of your link.

Figures 4 and 5, below, show an ODU mounted to a mast. In Figure 5, the mount’s elevation arms are positioned so the ODU points downwards.

Figure 4 Back View of ODU Mounted to a Mast


Figure 5 Side View of ODU Mounted to a Mast (Pointing Down)

Attaching the Mount on the Mast This section illustrates installation on a vertical mast. A horizontal support is also perfectly acceptable.

1. Cut the length of rubber collar material (using a sharp knife) so that it wraps around your mast with a small gap (.10 - .25 inch) between the ends.

2. Select the proper size hose clamp and install the rubber collar securely on the mast. This collar is used to hold the weight of the Outdoor Unit during installation and antenna alignment.

3. The bolts and hardware supplied will accommodate masts from 1.9 to 3.5 inches in outside diameter.

4. Use a safety rope or second person to hold the ODU in position on the mast, resting on the rubber collar. Install the top clamping yoke first. Install the bottom yoke last.

Note: Be careful not to drop the ODU. The weather seals protecting the antenna and microwave transceiver can be damaged.

Visually aim the antenna as precisely as possible in azimuth and elevation (i.e., both horizontally and vertically). Use a map and compass to set the correct direction. Tighten both yokes and elevation arms securely until ready for antenna aiming.


Grounding the ODU and Mast For safety and error-free performance, the ODU must have a proper electrical path to an earth ground (not to an electric utility ground). A ground lug is provided on the ODU.

Do not assume that the pipe on which an ODU is mounted will provide an adequate electrical path to earth ground. A visual inspection of the entire electrical path to earth ground is recommended.

A building’s electrical system ground is typically not a good earth ground because it can have high current flows due to an imbalance in the distribution of the single-phase load throughout a building. Those current flows typically result in voltage differentials along the electrical system ground. Ground loop currents result if two pieces of equipment are grounded to the electrical system ground and there is a voltage difference between the ground points.

It is important that the Stratum IDUs and ODUs are grounded to an earth ground that does not create a voltage difference between the IDUs and ODUs.

Damage to Stratum IDUs or ODUs caused directly or indirectly by lightning is not covered under the manufacturer’s warranty.

In addition to providing proper grounding for the system, Proxim recommends that lightning surge protectors for the DC power cable be used to protect the Stratum equipment from lightning strikes. Lightning surge protectors should be installed at both the ODU and building-entrance ends of the DC power cable, and properly connected to earth ground with #10 or #8 gauge wire at both points. A lightning surge protector is shown in Figure 6 below.

PolyPhaser Corporation (http://www.polyphaser.com) offers a Current Loop protector meeting the specific DC power feed requirements of the Proxim Stratum product family. The PolyPhaser Part Number is 099-1012P-A.

Figure 6 Lightning Surge Protector


Installing and Mounting the ODU-B-EXT The ODU-B-EXT includes an N-Connector for use with an external parabolic antenna, as shown in Figure 7 below.

The mounting procedure for the ODU-B-EXT is identical to the mounting procedure for a standard ODU except polarization is established by the rotation of the antenna feed horn, not by the position of the ODU. Check instructions packed with the parabolic antenna for polarization setting.

LMR-600 type cable is recommended for connecting the ODU-B-EXT to a parabolic antenna in order to minimize cable insertion loss.

Fiber Cable Connections Stratum is designed for fiber-optic interfaces between the IDU and the ODU to enable Fast Ethernet-speed connections over a distance of up to 1000 feet with an 8 dB light budget.

The Stratum Outdoor Unit (ODU) is suitable for weather-exposed installations with ambient temperatures of –30º to +55º C, in full sun and rain conditions. The Alignment Mounting Bracket (AMB) holds the ODU, aims the 18 inch square flat panel antenna, and attaches to a mounting pole. The ODU and AMB will withstand a wind-load of any periodicity and direction with wind force up to 80 miles per hour. Fiber-optic connections to the ODU, recommended below, are specified to address the same range of environmental conditions.

Each ODU includes two ST-type bulkhead connectors, one for the transmit fiber, one for the receive fiber. Proxim supplies with each ODU two ST connectors with custom boots designed to be weatherproof when properly installed on a sub-cable jacket with outside diameter of 2.7 to 3.0 mm. These connectors are part of the Fiber Termination Kit described in the following section. (If it is not feasible to use these connectors, then you must use some other means of weatherproofing the ST interface. For example, you can also use heat-shrink tubing over the entire connector with silicone rubber to seal both ends of the heat-shrink tubing and keep moisture out of the ST interface.)

Any FDDI-grade fiber may be used which meets the following requirements:

1. 62.5/125, multi-mode fiber with a bandwidth of at least 160 Mbps.

2. Kevlar strength member to allow pulling without damage to the fibers.

3. Cable jacket with UV inhibitor if cable is run outside a conduit.

4. Sub-cable jackets with UV inhibitors if sub-cable is fanned outside a conduit.

Breakout type cable is highly recommended for outdoor fiber runs due to its strength and weather resistance. Breakout cable can be connected directly to the ODU ST connectors provided the breakout sub-cables meet the requirements stated above.

Fiber Termination Box Proxim offers an optional Fiber Termination Box (FTB), which provides a weatherproof enclosure for termination of fiber runs.

The FTB includes:

• Box and cover with seal

• Cable grip for fiber cable from IDU

• Fiber jumper for connection to ODU

• Cable grip for fiber jumper to ODU

• Internal bulkhead patch panel and connectors

• Sealed mounting screws to attach the FTB to Stratum Alignment Mounting Bracket (AMB)

The FTB includes a set of installation instructions. In addition, specifications and installation instructions for the FTB are available on Proxim’s Web site.


A cover encloses the FTB and protects the sub-cables. Figure 9 below shows the FTB with its cover in place; Figure 10 shows the FTB without the cover.

Figure 9 Fiber Termination Box (with cover)

Figure 10

Fiber Termination Box (without cover)


Fiber Termination Kit Two Fiber Termination Kits are packed with each ODU at the factory for installations where a breakout cable is attached directly to the ODU. This Fiber Termination Kit is designed to accommodate fiber cable with a 2.7 to 3.0 mm outside diameter jacket. Contact Proxim Technical Support to check availability of alternative fiber cable termination arrangements if you wish to use another type of fiber cable.

Each kit contains four items, shown in Figure 11 below:

• ST Connector

13. Slide the rubber sleeve over the crimp so that the sleeve rests against the boot.

Note: Always inspect and clean fiber connectors prior to connecting to the equipment. Dirty connectors can contaminate equipment’s optical interfaces


Step 3. Installing the IDUs

Environmental Requirements The IDU requires a protected environment with its temperature maintained between 0º and 50º C (32º– 122º F), and less than 95% relative humidity, non-condensing. The environment should be free from extremes in temperature, dust, humidity, shock, vibration, and RF fields to ensure the IDU’s operation within published specifications.

Because the IDUs have cooling fans, they can be rack mounted or stacked without spaces between them. A clearance of at least one inch on both sides is required for ventilation. Be sure that the ventilating perforations on the sides and rear (near the connectors) are not blocked by cables or other equipment. Better ventilation, resulting from air space around the IDU, improves equipment reliability.

Unpacking and Installing the Hardware 1. Remove the IDU from its shipping carton.

2. Locate and set aside the accessory kit (with cables and mounting hardware) supplied in this carton. Save all packing materials in case you need them later.

3. Read the FCC Regulatory Compliance notice and Safety Warnings at the beginning of this manual.

IDU Accessory Kit Packing List

The IDU Kit contains

• Rack mounting brackets and hardware

• Rubber mounting feet (for tabletop use only)

• AC power cord

• Connector for IDU-ODU DC power cable

• RJ-45-to-DB-9 console adapter


Rack Mounting the IDU

Three sets of bracket holes for rack mounting allow the IDU to be mounted with its connectors facing the rear or front, as shown in Figure 13 below. The center set of holes also allows the IDU to be mounted in center rail racks or on the surface of a wall if the brackets are installed facing down.

Attach the two rack mounting brackets on each side of the IDU. Use four #8-32x1/2” Pan Head screws and #8 lock washers (under the screw head) for each bracket. Tighten the screws securely.

Mount the IDU in an equipment rack near the networking equipment (hub, server, switch, or router) to which it will be connected. Use two #12-24x3/4” screws in each rack bracket to mount the unit.

Figure 13

Side View of IDU

Precautions when Rack Mounting the Stratum IDU

When rack mounting your Stratum IDU, you should take the following precautions for safety and to ensure proper operation of the equipment:

The maximum ambient temperature for the Stratum IDU is 50º C. When installed in a rack, whether closed or open, the ambient temperature within the rack should not exceed 50º C.

Stratum IDUs have fans and ventilation holes to ensure proper air flow and maintain correct internal temperature. Do not block the fans or ventilation holes.

When mounting any equipment in a rack, you must consider the mechanical loading of the rack. Heavier equipment should be placed near the bottom of the rack and equipment should not be mounted in such a way as to cause instability. Special precautions should be taken with mountings that slide out for easier access to equipment. Such mountings can cause instability resulting in unsafe conditions and possible tipping of the rack.

Ensure that the power source, wiring, and over-current protection to rack mounted equipment is rated such that it can support the cumulative load of all equipment. Do not exceed the capacity of the wiring or over-current protection.

Reliable grounding of the Stratum is required.

The rack should also be grounded. If power distribution strips are used, ensure that they are properly grounded as well.


Tabletop Installation of the IDU

For installing the unit on a tabletop, attach the (4) self-adhesive rubber feet to the bottom of the unit near the corners. Do not attach the rubber feet if you are rack mounting the IDU.

Accessing the User Interface Software

Connecting the Management Console

Attach one end of the serial cable to the RJ-45 CONSOLE port connector on the rear of the IDU.

Install the RJ-45 to DB-9 adapter on the other end of this serial cable.

Connect the DB-9 adapter to your PC or laptop’s COM port.

You must use the DB-9 adapter supplied by Proxim, even if you use a DB-9 to DB-25 adapter to match your PC or laptop’s COM port. The adapter supplied by Proxim converts the RJ-45 CONSOLE port wiring to standard COM port wiring.

To setup the Stratum for the first time, open a VT-100 terminal emulation program, like HyperTerminal, on the PC to which you connected the serial cable. The communications settings for the console terminal must be:

• 9600 baud

• 8 bits

• No parity

• 1 stop bit

• No flow control

• VT-100 emulation

Alternately, you may use a VT-100 terminal to setup the Stratum.

If you use a PC running a VT-100 terminal emulator, make sure that the emulator uses the arrows for VT-100 commands, not for Windows operation. If the arrow keys do not work properly, use the Tab key to move between fields. Also, some terminal emulators, like HyperTerminal, default to “auto emulation.” You may need to manually configure the session to use VT-100 as the emulation type within the Settings tab of the session’s Properties screen.

Turning on the IDU

After mounting the IDU and connecting the serial cable, turn on the power switch. The Stratum will perform an internal set of power-up diagnostics and you will see a display like the one shown below.

Ethernet Parameters

Note 1: The RJ-45 port and the MII port cannot be used simultaneously.

Note 2: The MII port is intended for use with 100 Mbps full duplex fiberoptic transceivers. If you intend to use a 10 Mbps half duplex connection, you should connect the Ethernet network to the IDU using the RJ-45 port to ensure compatibility with all standard 10 Mbps PHYs.

Auto Negotiation, Speed, and Duplex settings:

If you intend to use the RJ-45 port, Auto Negotiation can be set to Enabled or Disabled. If Enabled, the speed and duplex of the Ethernet port will be automatically negotiated between the Stratum IDU and the connecting Ethernet device. If Disabled, the speed and duplex of the Ethernet port can be set by the user.

If you intend to use the MII port with a Fiberoptic transceiver, Auto Negotiation should be set to Disabled, the Speed should be set to 100 Mbps, and the Duplex should be set to Full-Duplex. Also, configure the MII Fiberoptic transceiver to a PHY address other than “17” to avoid conflict with the IDU’s internal PHY address.

IP address and Subnet Mask settings:

Assign an IP address to each Stratum IDU. This allows remote management without a direct cable connection to the console port. A unique IP address should be assigned to the IDU at each end of a Stratum link. The IDUs at both link ends must be in the same subnet.

Also note that while the Stratum appears to use only one IP address, it actually uses two IP addresses. The end-user/installer configures the Stratum with an IP address in the Ethernet Configuration screen. This IP address is used to identify the Stratum on the Ethernet network (an SNMP workstation will report this IP address as belonging to the Stratum’s Ethernet interface).


However, the Stratum will also automatically assign its radio port (port rf0 on an SNMP workstation) an IP address that is exactly 1 subnet higher than the one listed within the Ethernet Configuration screen. This second IP address is implemented for security purposes and is used in conjunction with CHAP (the Challenge Handshake Authentication Protocol).

For example, if you assign the Stratum an IP address of 192.168.0.100 with a subnet mask of 255.255.255.0, it will automatically assign its RF port an IP address of 192.168.1.100.

Be sure to reserve this second address so that there is no conflict with other devices on the higher subnet. Also, you may want to filter this second IP address from your SNMP workstation so it will not appear as an entry on the device map.

VLAN settings:

In addition to standard-sized Ethernet packets, the Stratum can support larger VLAN and Cisco interswitch link (ISL) packets. If you have a virtual LAN configured on your network, configure the Tag Bridging parameter to Enabled and configure the Stratum to use your network’s VLAN ID.

Spanning Tree State setting:

To enable the spanning tree features of the Stratum, configure the Spanning Tree State parameter to Enabled. Once Spanning Tree State is enabled, you can configure the other spanning tree parameters. The table below lists the spanning tree parameters, their default values, and range of acceptable values.

Field Default Range Hello Time (seconds) 2 1-10 Forward Delay (seconds) 15 4-30 Max Age (seconds) 20 6-40 Bridge Priority 32768 0-65535 Port Cost 100 1-65535 Port Priority 128 0-255

Choose [Âpply] or press Ctrl-A to apply your changes.

Once you have configured all of the necessary parameters within the Ethernet Configuration menu, press the down arrow until [ÔK] is highlighted. Press Enter to accept and save your changes. If you do not choose [ÔK], your changes will not be saved.


Setting Antenna Aiming Mode, Transmit Power, and the Link Security ID

Within the System Administration menu, use the down arrow key to select [Link Setup..] and press Enter to view the Link Set-Up menu, shown below.

----------------------------------- Link Set-Up ------------------------------- System Status: AIMING - NOT CONNECTED - ALARM NEW [ Alarms & Events.. ] ----------------------------- Link Parameters --------------------- Transmit Power Level: [Low ] Link ID: [DEFAULT ] Antenna Aiming: [Enabled ] [ Âpply ] [ ÔK ] [ ^Cancel ] ------------------------------------------------------------------------------

Using the space bar to toggle between the available options, specify the Transmit Power Level to either low or high power. Typically, low power is used for links spanning less than approximately 500 feet and high power is used for links over longer distances. The appropriate power setting should have been determined during the path survey.

Enter a 10-character value for the Link ID field. A valid Link ID is one to ten alphanumeric characters. The Link ID is case sensitive. Note that spaces, commas, periods, etc. are not valid characters to use within a Link ID. The Stratum uses the Link ID with the Challenge-Handshake Authentication Protocol (CHAP). For any given Stratum link, both IDUs must have the same Link ID. Each Stratum link should be given a unique Link ID.

Next, set the Antenna Aiming field to Enabled.

Apply any changes you have made and then use the down arrow to move to the [ÔK] field and press Enter to return to the System Administration menu.

Never attempt to reset the Stratum to factory defaults while in Antenna Aiming mode. See “Restoring Factory Defaults” on page 75 for details.

Setting up the Second IDU The installation for the second IDU is identical to the procedure for the first IDU, described above. Use the same Link ID for the second IDU.

Also, for remote management purposes, be sure to configure the second IDU with a unique IP address that is on the same IP subnet as the first IDU’s IP address.


Step 4. Aiming the Antennas

Aiming the First Antenna

1. Loosen the Bolts

Use a ½-inch socket wrench to loosen the bolts on the antenna mount. Make sure that the bolts on the upper and lower yokes have been loosened just enough to be able to rotate the antenna on the mast. The rubber collar supports the weight of the Outdoor Unit during aiming.

2. Set Azimuth in Center of Peak Signal

Slowly (over about 5 seconds) sweep the ODU in azimuth (side-to-side) covering a 90-degree arc.

Use the ODU’s BNC connector and a digital multi-meter (DMM) to aim the antenna. The ODU’s BNC connector provides an aiming voltage (0 – 5 VDC) that allows you to estimate the strength of the received signal. Use the digital multi-meter (DMM) to determine the antenna’s position that corresponds to the greatest RSSI (Received Signal Strength Indicator) value. The graph below shows the relationship between voltage and RSSI.

e


As an alternative to using the ODU’s BMC connector and a digital multi-meter, watch the ODU’s Aiming LED carefully to find the edges of the peak signal as you slowly sweep the ODU from side-to-side. The aiming LED, located on the ODU, will blink in the following ways to indicate signal strength:

1. On (solid) means the ODU is being supplied power but is not set in aiming mode.

2. One long flash every 5 seconds means that the local unit is in aiming mode but is not able to lock on the aiming signal from the other end. This behavior will also occur when one of the units is transmitting, but the other is not.

3. Three quick flashes per second means the local unit is locked on the aiming signal but is not aimed in the peak region (within 6 dB of the highest signal detected so far). Both ends are transmitting.

4. Fifteen quick flashes per second means that the local unit is locked on to the aiming signal and is aimed in the peak region (within 6 dB of the highest signal detected so far). A sampling circuit “remembers” the highest level detected as you scan the antenna from side to side and top to bottom, allowing you to record and find the “edges” of the peak region.

5. One quick flash every 10 seconds means the unit is in normal operation, not in the aiming mode.

6. Off (solid) means the unit is off or has a cable fault.

The peak signal value is stored as the antenna sweeps from side to side. The LED is a guide back to the correct peak value.

Proxim recommends that two people assist with aiming, one positioned at each antenna, and that they use cell phones to coordinate their efforts. Note that if you follow this procedure, take care to move only one antenna at a time. Alternately, aim one antenna and then go to the other site and aim the second antenna. To position the antenna exactly in the center of the peak signal region, use a permanent marker to identify where the edges of the peak signal correspond to the antenna’s position on the lower yoke or on the mast. Also, mark the location of the peak signal when position the antenna’s elevation, as described below.

Position the antenna in the center of the peak region. Tighten the upper and lower yokes securely on the mast.

3. Set Elevation in Center of Peak Signal

To determine the best elevation of the antenna, first loosen the two bolts holding the elevation arms at the angle bracket, the two bolts located at the slots of both arms, and the two pivot bolts at the top of the arms.

Slowly sweep in elevation (i.e., up and down) covering a 30-degree arc (centered on the line-of-sight path). Use a digital multi-meter (DMM) to measure the RSSI or watch the LED to find the peak signal while raising and lowering the antenna in elevation. Set the antenna in the center of the peak region.

Securely tighten the four bolts at both ends of the elevation arms. Also, securely tighten the two bolts on the upper angle bracket.

Aiming the Second Antenna Repeat the process described above to aim the second antenna in your link.


Verifying the Aim and Path Quality It is important to check signal strength and link performance before using the link for actual network traffic. This will ensure that your line-of-sight path and antenna aiming are satisfactory. To check signal strength, connect to the user interface of either Stratum IDU (as described in Step # 3, earlier in this chapter).

Receive Signal Strength Indicator (RSSI)

From within the main menu, select [Reports..] and press Enter to view the Reports menu, shown below. The Reports menu shows the RSSI value that represents the average signal level on all clear channels.

------------------------------------ Reports ---------------------------------- System Status: AIMING - NOT CONNECTED - ALARM NEW [ Alarms & Events.. ] System Name: Stratum System Uptime: 1999-04-30,09:19:04.0 IDU Temperature: 35 ODU Temperature: 37 RSSI: -54.8 Demod Status: Locked PLL Lock Status Locked [ T1 Channel 1 Status ] [ T1 Channel 2 Status ] [ LAN Status ] [ Session Status ] [ RF Link Status ] [ ^Cancel ] ------------------------------------------------------------------------------

A properly installed link will have an RSSI value that closely matches the value specified by the path survey.

Exiting Antenna Aiming Mode In the Link Setup screen, use the down arrow to select Antenna Aiming Mode. Press the space bar to toggle the mode from Enabled to Disabled.

Choose [Âpply] to save your change, and then choose [ÔK] to return to the System Administration screen.

Bringing the Link Up From the System Administration screen, use the down arrow to select the Link Up/Down field and then press the space bar to toggle its value to Up.

Note: The link will not be “up” until the Link Up/Down field is set to Up on both IDUs.

Choose [Âpply] to save your change, and then choose [ÔK] to return to the Main Menu screen.


Step 5. Connecting to Ethernet

Connecting the Hardware Note: The RJ-45 port and MII port cannot be used simultaneously.

If the RJ-45 port is used to connect the IDU to a hub or switch, use a straight through data cable. To connect to a router or a PC/server, use a crossover cable.

Connecting Ethernet to the Other IDU Connect an Ethernet cable to the second IDU following the procedure described above and earlier in this chapter. Use the console port to set the Ethernet parameters if you have not done so already.

Verifying Ethernet Connectivity Over the Link Connect to the console port to access the user interface, as described in Step #3 earlier in this chapter. From the Main Menu, use the down arrow to highlight [Diagnostics..] and press Enter to view to the Diagnostics menu.

-------------------------------- Diagnostics ---------------------------------- System Status: OPERATE - CONNECTED - OK NEW [ Alarms & Events.. ] -------------------------------- Ping Test ------------------------------------ Target IP Addr: [0.0.0.0 ] Target: Timeout (seconds): [0 ] Count: 0 [ Start_Ping ] [ Stop_Ping ] ----------- Loopback Tests ---------- ------- System Errors Test --------- T1 Ch 1: [DISABLE] Time: 0 T1 Ch 2: [DISABLE] Errors: 0 System: [DISABLE] Rate: 0 [ Apply_Loopback ] [ Start_SYS ] [ Stop_SYS ] -------------------------------- BER Tests ------------------------------------ Channel: [T1_Ch1 ] Test: [Mark ] Time: 0 Errors: 0 Rate: 0 [ Start_BER ] [ Stop_BER ] [ Reset_Counters ] -------------------------------- Other Tests ---------------------------------- [ View Power-On-Self-Test Results ] [ ^Cancel ] -------------------------------------------------------------------------------

To verify Ethernet connectivity, enter the IP address of the remote Stratum in the Target IP Addr: field. Set the Timeout value with the number of seconds to perform the ping test. Pings will be sent once per second for the specified time.

Use the down arrow to highlight [Start_Ping] and press Enter to begin the test.

As the test proceeds, the Target field will be updated to show if the target responded. This field will display No Answer if the target does not respond. If the target responds correctly, this field will display Alive.


Step 6. Verifying Correct System Operation To verify that the system is operating correctly, connect a PC to the serial console port of one of the IDUs and login to the system as described in Step #3, earlier in this chapter.

Viewing Status Information on the Main Menu At this point in the installation process, the System Status message should have changed.

The local unit’s System Status is displayed in the top left corner of each user interface screen, and reflects three characteristics: Current Mode, Connection Status, and Operating Status.

When the system is running correctly, you should see:

System Status: OPERATE – CONNECTED – OK

Step 7. Setting up the T1 Port The T1 ports on the Stratum are DSX-1 ports with RJ-48C jacks. To connect two DSX-1 (T1) devices, you need to make or locate a cable that is properly terminated with an RJ-45 plug on one end, with lead pairs corresponding to “transmit” or “receive” identified at the other end when terminated at the cross-connect block. Stratum is not approved for direct connection to public T1 lines without the use of an external CSU.

Proxim recommends that you install a cross-connect (punchdown) block between the Stratum and the T1 equipment. The T1s should be terminated at the cross-connect block per telephone industry standards.

Stratum supports both AMI (Alternate Marks Inverted) and B8ZS (Binary 8 with Zero Substitution) line coding schemes as well as D4 (SuperFrame) and ESF (Extended SuperFrame) frame formats for compatibility with most T1 equipment. Clocking is taken from the T1 device at each end and carried through the link to the device at the far end. Stratum’s T1s are clear channel, i.e., they are transparent to data, voice, and signaling contained within T1 frames.

Connecting T1 Devices To connect the Stratum’s T1 ports to a cross-connect block, you need to make or locate a cable that is properly terminated with an RJ-45 plug on one end, with lead pairs corresponding to “transmit” or “receive” identified at the other end when terminated at the cross-connect block. See Figure 16 for the pinout of the Stratum DSX-1 ports.

Figure 16

Stratum T1 Pinout

The “tip” and “ring” leads of both transmit and receive pairs must be terminated at the proper RJ-45 plug pin. A common cabling problem is that “tip” and “ring” can be reversed, and because the circuit impedance is balanced, the system may still work, but have ground loop and noise problems. If the ground loop or noise problem becomes severe enough, bit error problems can result. Be sure that you verify the equipment T1 wiring diagram, since it is not enough to simply connect the cable pairs to pins 1/2 and pins 4/5, as “tip” and “ring” leads need to be differentiated.

IDU


Proxim strongly recommends that you follow industry practice and install a cross-connect (punchdown) block between the Stratum and the T1 equipment. This simplifies cross connection between two T1 devices and eliminates cabling errors, by allowing the transmit “tip” from one T1 device to be “punched down” to the receive “tip” of the other T1 device at the cross-connect point. The same applies to the “ring” leads of both T1 devices. The cross-connect block also serves as a demarcation point between equipment from different vendors, and it is the point at which DSX-1 signal characteristics must be tested for compliance during troubleshooting. Therefore, any problems that arise with the T1 can be quickly isolated to being on one side of the cross-connect point or the other.

Note that all DSX-1 compliant equipment interfaces (like the Stratum’s) can be up to a cable distance of 655 feet from a cross-connect block. This requires the use of a proper cable (shielded, two sets of twisted pairs per T1, each with a balanced impedance of 100 Ohms). An example of such a cable is Belden 7839A, which can support up to three T1s.

Before configuring the T1 ports, determine the line coding and frame formats of the T1 devices you have connected to the IDUs.

Configuring the T1 Port To connect T1 devices through the Stratum link, you must first enable the Stratum’s T1 port or ports. Once the ports have been enabled, the IDU will generate alarms for the port and activate the interface. If you do not intend to use the T1 interface on your Stratum units, do not enable the T1 port, as this will generate false alarms for the system.

Select [T1 Config..] within the System Administration menu and press Enter to view the T1 Configuration menu, shown below. To enable a T1 port, use the down arrow to select the Channel 1 Enable or Channel 2 Enable field and use the space bar to toggle the setting to Enabled.

The Channel Software Key will already be entered at the factory. Do not change the Channel Software Key. Power resets or returning the unit to all factory defaults will not cause the Channel Software Key to be reset.

Do not change the Channel Software Key. The Channel Software Key must be left at its factory default setting; it is unique to each individual unit. If you change the Channel Software Key, then you will not be able to enable the Stratum’s T1 Channels.

Set the framing mode by moving the cursor to the appropriate Channel Framing Mode field and using the space bar to toggle between the choices. The choices are D4 and ESF and must match the frame format used by the attached T1 device. Likewise, set the Line Coding Format to match the line coding used the by the attached device.

The Stratum does not perform frame format or line encoding conversion, so both ends of the link and their attached T1 devices must use the same framing mode and line-coding format.

Reviewing T1 Performance and Error Reports T1 channel performance is monitored for the T1 line input to the Stratum from each connected T1 device.

From the Main Menu, select [Reports..] to display the Reports menu. Choose T1 Channel 1 Status or T1 Channel 2 Status to view status information for the selected T1 channels. A sample status report for Channel 1 is shown below.

Connecting to the Stratum

Using the Console Port The RJ-45 connector on the back of the Stratum labeled CONSOLE allows connection to any standard RS-232C terminal emulator that supports VT-100. This method requires physical access to one of the Stratum IDU units (both units, if the wireless link is not available).

Note: It is important to use the DB-9 adapter supplied by Proxim, even if you use a DB-9 to DB-25 adapter to match your PC or laptop’s COM port. The adapter supplied by Proxim converts the RJ-45 CONSOLE port wiring to standard COM port wiring.

The simplest way to access the console is to connect the IDU to a PC running a VT-100 terminal emulator, such as HyperTerminal. The communications settings for the console terminal must be:

• 9600 baud

• 8 bits

• No parity

• 1 stop bit

• No flow control

• VT-100 emulation

Alternately, you may use a VT-100 terminal. Note that some terminal emulators, like HyperTerminal, default to “auto emulation.” You may need to manually configure the session to use VT-100 as the emulation type within the Settings tab of the session’s Properties screen.

Once the PC is attached to the console port and the power is turned on, the login screen will appear, as shown below.


Entering the Password

The Stratum is preset at the factory with the following Access Level and Password:


Password: wavespan

The password is case sensitive.

Once the Access Level and Password have been successfully entered, the Main Menu will appear.

The VT-100 interface is described in the section entitled Navigating in the VT-100 User Interface, later in this chapter.


Using Telnet and a VT-100 Terminal Emulator If you have configured a Stratum IDU with an IP address, then you may also use Telnet to access the management menu. Open a Telnet program and type in the IP address of the Stratum. Once the Telnet connection has been established, the login screen will appear, as shown below.


Entering the Password

The Stratum is preset at the factory with the following Access Level and Password:


Password: wavespan

The password is case sensitive.

Once the Access Level and Password have been successfully entered, the Main Menu will appear, as shown below.

The VT-100 interface is described below in the section entitled Navigating in the VT-100 User Interface.

Navigating in the VT-100 User Interface The text-based user interface uses standard VT-100 conventions.

Moving the Cursor

The Up/Down arrow keys move the cursor to the next or previous selection. The Tab key also advances the cursor to the next selection.

Some terminal emulators use the arrow keys for commands in their native environment. Be sure to enable the arrows to send VT-100 codes in order to use the Stratum interface most effectively.


Selecting Menu Choices and Commands

Selectable items are shown in square brackets. For example,

[Modem Status]

Read-Only Fields

These fields display information that cannot be edited in the current screen (although you may be able to edit the information in another screen). The cursor will not highlight Read-Only fields.

Editable Fields

You may enter any alphanumeric characters in Editable Fields. The backspace key can be used in these fields. You must press Enter before going on to register the new contents.

Toggle Fields

Use the space bar to choose between available options. (Do not press Enter after setting a toggle field).

Applying Changes

Type Ctrl-A (or move the cursor to [Âpply] and press Enter) to apply changed settings without exiting the screen. Changes only take effect if you apply them. Type Ctrl-O (or [ÔK]) to apply changes and exit to the previous screen. Some changes in the Link Setup screen will automatically reboot the system when they are applied (in these cases, a prompt will appear to notify you that a reboot is required).

Exit to Previous Screen

Type Ctrl-C to exit the current screen and go back to the previous screen. Any changes you made will not be retained after exiting the current screen.

Other Key Sequences

The following Ctrl key sequences work within most of the Stratum’s configuration menus:

^R Refresh the screen ^C Cancel current changes

Â Apply changes Û Update (updates values on Reports screens)

Ô OK (saves changes and exits to the previous screen)

Using a Web Browser The Stratum’s configuration interface can be accessed with a Web browser that supports frames and JavaScript (e.g., Netscape 3 Gold, Netscape 4, and Internet Explorer 4).

Specify the IP address of the Stratum in the Address field of the browser, and the HTML interface will appear as shown in the following example.


Note: If you are using a browser from Netscape, ensure that the Java Script is enabled on the browser or the login attempt will fail.

Click the Login button and you will be prompted to enter your access level and password.

Once you have logged in to the Stratum, the Main Menu will appear, as shown below.


The browser interface is similar to the VT-100 interface, except that the menu choices are listed in the column on the left-hand side of the screen. The browser’s Configuration heading replaces the VT-100’s System Admin menu.

Differences between the Web Interface and the VT-100 Interface

The following features can only be accessed from the VT-100 interface:

1. Access to remote IDU (console port only)

2. Accessing the interface when no IP address has been configured (console port only)

3. Changing the settings for the console port

4. Terminating user sessions (web browser only)

Note that when using the VT-100 interface, selectable fields can be changed by using the spacebar to cycle through the available settings. On the HTML interface, a drop-down menu is provided.

Also note that when using the VT-100 interface, choose [Âpply] to save settings and then [ÔK] to return to the previous screen. On the HTML interface, simply click Apply to save changes.

Accessing a Remote Stratum From a Local Stratum (Through the Wireless Link) When connected to a Stratum’s VT-100 interface, you can access the interface of the remote unit if the wireless link is up and operational.

Note that you can only access a remote Stratum via the console port. You cannot access a remote unit via Telnet or the Web browser interface.

When connected to the local Stratum via the console port, choose [Remote] from the local IDU’s main menu to login to the remote Stratum.

The login screen for the remote unit will appear. If the login screen does not appear, press ^R to refresh the screen.


Navigate through the VT-100 interface as described in Navigating in the VT-100 User Interface.

If the connection attempt fails, you may find that you are no longer able to access the local Stratum. In this case, close the remote session by holding down the Ctrl key and pressing the ] key.


Commands to Avoid when Using Remote Access

When accessing a Stratum remotely, do NOT use the following commands:

Command to Avoid Reason

Running a Loopback Test

Remote unit will no longer respond to the local unit and the remote unit will need to be reset through the console port or the Ethernet link.

Link Down Ends the remote link so that the unit cannot be accessed remotely.

Changing IP Addresses

Ends session.

Ending the Remote Session

Select [Remote Exit] to terminate the session and return to the main menu of the local Stratum.

Using SNMP to Access the Stratum Once the Stratum is installed, SNMP can be used to manage and monitor it. To enable traps by your SNMP manager, first access the Stratum through some other method (e.g. through the console port) and configure SNMP access as described below.

The Stratum supports MIB-II, RFC 1213, RFC 1406, and the Stratum MIB. Once SNMP access has been configured, any standard SNMP management tool can be used to monitor performance.

Configuring SNMP Management

-------------- VT-100 --------------

To enable SNMP management, select [System Admin..] from the main menu. Then choose [SNMP] from the System Administration screen.

------------------------------- SNMP Management --------------------------- System Status: OPERATE - CONNECTED - OK [ Alarms & Events.. ] Read Community String: [public ] Write Community String: [private ] Trap Community String: [snmptrap ] SNMP Trap Destinations IP Addr Screening ---------------------- ---------------------- [0.0.0.0 ] [0.0.0.0 ] [0.0.0.0 ] [0.0.0.0 ] [0.0.0.0 ] [0.0.0.0 ] [0.0.0.0 ] [0.0.0.0 ] [0.0.0.0 ] [0.0.0.0 ] SNMP Agent: [Disabled] IP Screening: [Disabled] [ Âpply ] [ ÔK ] [ ^Cancel ]



To enable SNMP management, click Configuration and then choose SNMP from the submenu to view the SNMP Configuration screen, as shown in the partial screen shot below.

-------------------------------------


The following table describes the available SNMP Management/Configuration parameters:

Field Description

Read Community String

The Stratum responds only to GET requests whose community string value matches this field.

Write Community String

The Stratum responds only to SET requests whose community string value matches this field.

Trap Community String

All alarm messages are sent with this community string.

SNMP Trap Destinations

The network management workstations with the IP addresses in this list will receive alarm traps.

IP Addr Screening The Stratum will accept SNMP GET and SET requests from these IP addresses only. These values will be ignored if the IP Screening field is set to Disabled.

SNMP Agent If this field is set to Disabled then all SNMP management functions are disabled.

IP Screening If this field is set to Disabled then IP address screening is disabled. If this field is set to Enabled, then only the five IP addresses in the IP Addr Screening table can access the Stratum through SNMP; normal SNMP requests using the Read and Write Community Strings will fail unless performed by one of the authorized IP addresses.

Configure the above parameters as necessary within the SNMP Management screen. Then, choose the SNMP Agent field and use the space bar to toggle the value to Enabled (VT-100) or use the drop-down menu (HTML) to enable this option.

Choose Apply to save changes.


Reading the Status Information on the Main Menu Local unit System Status is displayed in the top left corner of each user interface screen and reflects three characteristics: Current Mode, Connection Status, and Operating Status.

When the system is running correctly, the following message should appear:

OPERATE – CONNECTED – OK

If you see a different message, refer to the information below to determine its significance.

Current Mode

• Operate – means the RF link is up.

• STBY – means the RF link is currently down.

• Aiming – means the RF link is down and Antenna Aiming Mode is Enabled.

Connection Status

• Connected – means the local and remote IDUs are connected to each other.

• Not Connected – means the link is not connected.

• Connecting – means the local IDU is trying to connect.

Operating Status

• OK – means that all operation is normal, no active alarms.

• Alarm – means that an alarm condition is currently active.

• Under Test – means that the system or user has launched a test that is currently underway.


Setting Parameters A user configures the Stratum within the System Admin menu (VT-100) or the Configuration menu (HTML).

The parameters and menu choices are the same in both interfaces. Differences between the two interfaces are noted in the appropriate sections of this manual.

Viewing Alarms and Events

ODU Link Failure A Control and monitoring communication between the IDU and ODU has failed.

Loss of Signal Failure A T1 error, no signal present.

Loss of Frame Failure A T1 signal present, but no frame.

Alarm Indication Signal A T1 signal present but unframed. This can occur when the other end has T1 disabled or there are problems with the upstream device.

ODU Temperature Alarm A The ODU temperature has exceeded 75 degrees Celsius (167 F), which can cause catastrophic equipment failure. At this temperature, the unit should be shut down.

IDU Temperature Alarm A The IDU temperature has exceeded 75 degrees Celsius (167 F), which can cause catastrophic equipment failure. At this temperature, the unit should be shut down.

RF Link Down – Manual E This event occurs when someone has manually set the Link Up/Down field to be Down.

Antenna Aiming Started/Ended E This event happens when someone has initiated/terminated Antenna Aiming mode from either end of the link.

Cold Start E The IDU has been reset. Some configuration change has occurred since the last reset was updated and the unit was restarted.

Warm Start E The IDU has been reset.

RF Link Up E The local IDU has established communication with the remote unit.

System Diagnostic Started/Ended

E This event happens when someone initiates/terminates system diagnostics.

Defaults Restored E The user has restored default values from the Utilities screen.

Authentication Failure E An SNMP packet with an unmatchable community string has been received by the IDU.


Running Diagnostics

Running Diagnostic Tests The Stratum provides several tests to aid in the diagnosis of system components.

Ping Test

The Ping test determines if a Stratum unit can communicate with another IP address. The specified number of pings is sent to the target address and the results are displayed in the VT-100 or web browser window. If a ping test is performed with the remote Stratum unit, then the test exercises the full wireless link.

Loopback Test

The Stratum provides system-level loopback tests to test the IDU or ODU. The IDU test functionally isolates the IDU from the ODU and internally connects its Tx output to its Rx input. Packets are then sent on all channels verifying correct operation. The ODU test electrically isolates the IDU-ODU cables from the radio and connects the two cables together inside the ODU. Note that loopback tests can only be done when you are connected through the console port. Loopback tests must be performed when the link is in STBY (standby) mode.

BER Test

There are three Bit Error Rate tests: the IDU Loopback, the ODU Loopback, and the T1. The Diagnostic screen reports how long a particular test has been running, the number of errors encountered, and the bit error rate in scientific notation form (e.g., 5 x 10-8). The IDU and ODU Loopback tests require that the Stratum be in STBY (standby) mode. The IDU test internally connects the IDU’s Tx output to its Rx input and runs a test pattern. The ODU test is very similar and connects the ODU’s two cables together and runs a test pattern recording the same information as the IDU test. For these tests, set the Test parameter to either Mark or Space. The test uses parity checking to identify single bit errors. When set to Mark, the Parity bit is asserted in each line sent. When set to Space, the parity bit is unasserted. These two test methods should yield similar results.

The T1 test sends a test pattern from one Stratum T1 to another radio’s T1 across the wireless link. The test runs without impacting user data and is unidirectional so you can run the test from both ends simultaneously or from one end at a time to determine if there is a problem and on which side. For this test, set the Test parameter to QRSS (Quasi-Random Signal Source), which is the most commonly used test pattern for T-1 maintenance and installation.

System Errors Test

The System Errors Test utilizes the forward error correction (FEC) data to determine whether or not the aggregate transmitted data contains uncorrectable errors. The test reflects the path direction towards the IDU that has the system errors test enabled. Therefore, it reflects the equipment AND any path interference or distortion effects. This test is more thorough than running the T1 BER test and it is non-intrusive with respect to customer payload data. Also, since the test is unidirectional, it allows diagnosis of path quality (such as marginal C/I or Fade Margin) in each direction.

The System Errors Test runs at maximum speeds (e.g., >100 Mbps for the Stratum 100) and can be set up to run independently in both directions at the same time. Proxim recommends that you let the test run for at least 2 hours, and if there are no errors reported by that time, the Stratum equipment is functioning properly and the radio link is strong. The test reports how long the test has been running, the number of errors encountered, and the bit-error rate in scientific notation form (e.g., 5 x 10-8). A successful System Errors Test is one with zero errors. Any errors indicate that the system is operating on the threshold and about to go down.

Power On SelfTest

Choosing this option shows the results of the self-test diagnostics that were run when the unit was last restarted.
