General Safety GuidelinesAdhere to the following general safety guidelines at all times during installation and service:

Only trained personnel should perform installation, service and maintenance of the TN780 and Opti-cal Line Amplifier network elements.

Exclude all unauthorized personnel from the immediate area of installation and service.

Keep the chassis area clear of obstructions and dust-free before, during, and after installation.

Keep tools and equipment away from walk areas.

Do not wear loose clothing or any other items that might be caught in the equipment during installa-tion and service.

Secure long hair.

Never attempt to lift any object alone that might be too heavy for one person to lift safely.

Locate the emergency power-off switch for the room in which you are working.

Be aware of possible hazards in your work area, such as wet floors, ungrounded power extension cords or missing safety grounds.

Do not work alone if potentially hazardous conditions exist anywhere in the work area.

Arrange for sufficient air circulation or space between units when the network element is installed in a closed or multirack assembly. The maximum recommended ambient temperature for the network element is 55oC (131oF). Note that the operating ambient temperature of the rack environment might be greater than room ambient.

Do not cover slots and openings in the chassis (provided for ventilation) to ensure reliable operation of the network element and to protect it from overheating.

Consult with the appropriate regulatory agencies and inspection authorities to ensure compliance. The final configuration of the product must comply with the applicable safety standards and regula-tory requirements of the country in which it is installed.

Jewelry Removal WarningBefore working on equipment that is connected to power lines, remove jewelry including rings, necklaces, and watches. Metal objects heat up when connected to power and ground, and can cause serious burns or become welded to terminals.



Electrical SafetyThe Digital Transport Chassis (DTC) and Optical Transport Chassis (OTC) each have two power entry modules (PEM A and PEM B), which accept an input voltage ranging from −40V DC to −60V DC. These chassis also have connectors on the shelf backplane to provide a DC voltage supply to the circuit packs installed in the chassis. The following precautions must be observed while handling this equipment:

CAUTIONRisk of electrical shock.Personal injury can be caused by –48 VDC.Take appropriate precautions.

The connections and equipment that supply power to the DTC and OTC must be capable of operat-ing safely within the maximum power requirement of the equipment. In the event of a power over-load, the supply circuits and supply wiring should not become hazardous.

The input rating (70 A) of the DTC is labeled on the DTC PEM as shown in Figure 1-1 on page 1-5.

Figure 1-1 DTC Power Entry Module

The OTC PEM is connected to the Power Distribution Unit (PDU). The PDU must have a 10 A circuit breaker.

Ground the DTC and OTC in compliance with local and national electrical codes. The DTC contains four electrical ground points: two in the rear and two on the front sides for forward mount grounding. The OTC contains two electrical ground points, located at the rear bottom of the chassis.

Never connect or disconnect the power-input cables to the PEM when the other end is connected to the power supply.

Prior to install, verify that PEM A and PEM B on the DTC and OTC are not receiving power.

Do not use both hands when working on or near a voltage source.

Use the buddy system when working around voltage sources.

PowerOn/OffSwitch

PowerLEDs



Never remove a PEM while power is applied. Turn off the circuit breaker or the PDU, turn off the power at the Battery Distribution Fuse Bay (BDFB), and disconnect the power-input cables before removing the PEM.

Some of the connectors on the shelf backplane present an electrical hazard. Never reach into a shelf with a conductive tool or your bare hand when power is applied to the equipment.

The DC power source to the PEM must comply with the Safety Extra-Low Voltage (SELV) require-ments specified in UL 60950.

Install the equipment in compliance with appropriate local and national electrical codes.

In the United States, use National Fire Protection Association (NFPA) 70 and the United States National Electrical Code.

In Canada, use the Canadian Electrical Code, part I, CSA C22.1.

In other countries, use International Electrotechnical Commission (IEC) 364, parts 1 through 7.

UTStarcom equipment is intended for installation in restricted access areas. A restricted access area is one in which access can only be gained by service personnel through the use of a special tool, lock, key, or other means of security, and access is controlled by the authority responsible for the location.

Lifting Precautions

CAUTIONHeavy object.

The equipment is heavy. Unassisted or improper lifting techniques can cause personal injury. Take appropriate safety precautions.

Before installing any UTStarcom equipment, ensure that your site is set up so that you won’t have to move equipment later to provide direct access to power sources and other connections.

When lifting or handling materials manually, use only methods that ensure personal safety and protection of the equipment. Never attempt to lift objects that are too bulky or heavy to handle safely. Whenever possible, push loads instead of pulling them.

Whenever you lift or move any heavy object, take the following precautions:

Enlist the assistance of a second person. Do not attempt to lift them by yourself.

Secure your footing while lifting. Balance the lifted weight equally between your feet.

Lift the object slowly; avoid making sudden movements or twisting your body as you lift.

Keep your back straight and lift with your legs. If you must bend down to lift the object, bend your knees to reduce the strain on your lower back, and avoid bending solely at the waist.

Always disconnect all external cables before lifting or moving UTStarcom equipment.



ESD SafetyThe DTC and OTC have field replaceable modules that are susceptible to damage caused by static electricity that builds up on work surfaces and personnel. The effect of Electrostatic Discharge (ESD) damage may be immediate failure or it may manifest itself as a latent failure affecting the reliability of the equipment.

CAUTIONRisk of damage to equipment.The equipment is susceptible to Electrostatic Discharge (ESD). Use ESD grounding straps when handling equipment and follow ESD procedures.

Take the following precautions to avoid ESD damage:

Wear a grounded wrist strap or a heel strap and stand on a grounded static-dissipating floor mat when handling chassis, circuit packs, and cables and fibers connected to circuit packs.

Ensure that wrist straps and heel straps fit snugly, making firm contact with your skin. Ensure that the wrist straps and heel straps are tested.

Connect the grounding cord of the wrist strap to the ground jack provided on the front bottom right-hand side on the chassis.

Maintain relative humidity above 20 percent.

Laser SafetyThe DTC and OTC have circuit packs with laser sources that emit light energy into optical fibers. This energy is within the infrared (not visible) band of the electromagnetic spectrum. All optical circuit packs, such as the Band Mux Module (BMM), Digital Line Module (DLM), and the Optical Amplifier Module (OAM), have warning labels, as shown in Figure 1-2 on page 1-7.

Figure 1-2 Warning labels on circuit packs

CLASS 1M warning on BMM and OAM circuit packs

CLASS 1 warning on DLM circuit pack



The warning label on BMM and OAM circuit packs conveys the following information:

There are risks associated with hazards associated with exposed optical fiber ends and untermi-nated connectors. IA hazard can exist on either the fixed or free end of a connector, depending on the direction of transmission.

The line output on BMM and OAM circuit packs complies with CLASS 1M (IEC) and CLASS I (CDRH) standards.

The nominal wavelength is 1550 nm.

The line output power is 50 mW.

Digital Line Module (DLM) and Tributary Optical Module (TOM) circuit packs comply with CLASS 1 (IEC) and CLASS I (CDRH) standards. TOM circuit packs do not have a laser safety warning label.

Take the following precautions when handling optical circuit packs:

Never disconnect an optical fiber and look directly into the optical connector of the instrument.

Wear laser safety goggles whenever you are in close proximity to lasers.

Do not adjust lasers, as it could result in hazardous radiation exposure.



Handling Circuit Packs

All circuit packs have electronic components that are susceptible to damage due to improper handling or electrostatic discharge. Take the following precautions when handling circuit packs:

Do not remove the circuit pack from the shipping package until you are ready to install it.

Remove a circuit pack from its antistatic protective casing only once it is in the installation vicinity.

When circuit packs are not in use, store each one separately in an antistatic protective casing or original shipping container, even if the circuit pack is defective and you are returning it.

Wear a grounded wrist strap or heel strap before removing a circuit pack from its package or from a shelf, and before installing it in a shelf.

Never touch the electronic components of a circuit pack. Handle the circuit pack by the faceplate and the ejector, or by the handles on the faceplate.

Inspect the pin connectors on the circuit pack for any damage before inserting into a shelf.

Protect all optical connectors of the circuit packs with clean dust caps when fibers are not con-nected.

Allow the circuit pack to reach room temperature before inserting it into a shelf.

When transporting circuit packs, pack each circuit pack in its original shipping container and pad-ding, or in a shielded bag. If the original packing material is lost, use another antistatic protective container.

Handle circuit packs with care to prevent damage from accidental drops.

Do not attempt to disassemble or repair any of the circuit packs. The TN780 circuit packs are not field serviceable circuit packs. For more information or assistance please contact an UTStarcom Customer Service and Technical Support resource (see “Technical Assistance” on page xii).

CAUTIONOptical connectors can be damaged if their protective covers or dust caps are not installed when the connectors are not in use.

CHAPTER 2

Preparing for Installation

This chapter provides information on site preparation and considerations for installing Digital Optical Network network elements. This chapter is organized into the following sections:

“Environment” on page 2-2

“Power and Grounding” on page 2-4

“Seismic Considerations” on page 2-5

“Planning for Multi-chassis Install” on page 2-6

“Required Tools and Test Equipment” on page 2-8


Page 2-2 EnvironmentPage 2-2

EnvironmentThe installation site must meet the following requirements:

Rack — Customers must supply their own industry standard 23-inch or ETSI (European Telecom-munications Standards Institute, 600 mm) racks.

Rack Spacing — The rack must offer front access to the chassis with sufficient clearance to allow free access to all the circuit packs and PEMs. Minimum clearance between the front unit and any obstructions must be at least five feet. The unit’s depth is 12 inches (30.48 cm) without cable man-agement. With cable trays, cables and door, an additional 3.4 inches are required on the front of the unit. In addition to the cable tray, an additional 30 inches of clearance is necessary to remove circuit packs. If the DTC is installed inside an enclosed cabinet, the cabinet door must be perforated to 80 percent open.

Weight — A bare DTC weighs 75 lbs (34 kgs), requiring at least two people to mount the chassis into a rack. An OTC weighs 49.5 lbs (22.5 kgs) and a Dispersion Management Chassis (DMC) weighs 5.5 lbs (2.5 kgs)

Cooling — The chassis is self-cooling. Intake air comes from the bottom front and bottom side air intake plenums, and is discharged out at the top rear and top sides of the DTC. The OTC has the air intake from the front side and the discharge at the rear side. Be sure to install the chassis in a rack with adequate and unobstructed airflow.

Operating Environment — The network elements must operate in a cooled, humidity-controlled datacenter environment. The minimum and maximum tolerances are as follows:

Humidity — 5 to 85 percent relative humidity, non-condensing.

Normal Operating Temperature — 5oC to 40oC (41oF to 104oF).

Short-term Operating Temperature — Negative 5oC to 55oC (23oF to 131oF) without fan fail-ure and negative 5oC to 50oC (23oF to 122oF) with one fan failure.

Altitude — 5906 feet (1800 m).

Vibration — 0.1 g from 5-100 Hz and back to 5 Hz at 0.1 octave per minute.

Note: Elevated Operating Ambient Temperature - If the unit is installed in a closed or multi-unit rack assembly, the operating temperature of the pole/rack environment may be greater than the ambient temperature of the room.

Power Dissipation — Maximum power dissipation over the life of a fully loaded DTC is 2915.7 watts. Maximum power dissipation over the life of a fully loaded OTC is 251.6 watts.

Wiring to a Power Source — The PEM A and PEM B on a DTC are each connected by two power cables to a BDFB. On the OTC, PEMs are connected to the power distribution unit (PDU).

Electrostatic Discharge — The building should provide appropriate chassis grounding, pursuant to safety code. When handling circuit packs and components, take appropriate grounding precautions to prevent damage due to electrostatic discharge.


Page 2-3Preparing for Installation

Circuit Overloading — To maintain current protection and supply wiring, the supply circuit to which the network element is connected should not be overloaded.


Page 2-4 Power and GroundingPage 2-4

Power and GroundingObserve the following power and grounding requirements:

Maintain reliable grounding for the network element and all rack-mounted equipment, giving particu-lar attention to supply circuits.

Establish an explicit ground for the DTC and OTC by using a cable to make a connection between an approved building ground and the ground point located at the lower right and left rear corner of each chassis.

Verify all communications connections between the network elements and other equipment of differ-ent grounding topologies and ensure that they are metallically isolated from each other.



Seismic ConsiderationsNetwork element components, such as the DTC, OTC, and DMC, must be tightly secured to either an industry standard 23-inch rack or a 600mm ETSI rack to reduce the risk of damage during seismic activity.

The Digital Optical Network system elements are Network Equipment Building System (NEBS) Level 3 compliant and can be installed in seismic zones 1-4 (i.e., any zone).


Page 2-6 Planning for Multi-chassis InstallPage 2-6

Planning for Multi-chassis InstallIn a multi-chassis system, a single network element consists of a Main Chassis and one or more Expansion Chassis. These chassis are installed on a single rack, or in multiple racks. The installation of a multi-chassis system requires some degree of planning in terms of the physical location of the racks and chassis within those racks. This is also true for installing a chassis that must support the future addition of Expansion Chassis.

Take the following considerations when installing a multi-chassis layout:

Maximum interconnect cable length — In a multi-chassis configuration, chassis are intercon-nected at the nodal control and timing (NCT) ports of their respective input/output panels, using Cat-egory 5 (CAT5) Ethernet cables. The maximum certified length for NCT cables between any two interconnected chassis is 100 meters (328 feet). Therefore, when installing a multi-chassis system (or when installing a chassis that may later be interconnected to new Expansion Chassis), be sure the inter-chassis NCT port separation does not exceed 100 meters.

Number and location of chassis per rack — Unlike chassis, racks are not managed objects. Therefore, there are no restrictions on the number of chassis that may be installed in a single rack, other than what can physically fit into the rack. Similarly, there are no restrictions on the specific sub-rack location for each chassis.

Maximum allowed number of chassis — The physical installation layout should also consider the maximum number of chassis allowed in a multi-chassis configuration. The Digital Optical Network® system is designed to accommodate up to six chassis (the Main Chassis and up to five Expansion Chassis) on a single network element.

Note: Release 1.2 certifies up to two DTC chassis in a multi-chassis configuration. Future releases will certify up to six chassis on a single network element.

The standard configuration for a multi-chassis configuration is shown in Figure 2-1 on page 2-7.



Figure 2-1 Standard multi-chassis configuration

Note: NCT cables are not shipped with the DTC. Prior to installing a multi-chassis system, obtain the NCT cables required to interconnect your multi-chassis configuration. For more infor-mation about the type of cable and the correct number of cables to obtain, see “Installing Multi-chassis NCT Cables” on page 3-54. The length of the cables are determined by the inter-chassis spacing.

6” forward mount

Note: If the DTC is installed inside an enclosed cabinet, the cabinet door must be perforated to 80 percent open so that there is a proper ventilation from the front of the system.

Note: The ETSI rack mounting ears are part of the chassis. The external rack mounting ears are required for the 23-inch flush mount and forward mount configurations. The DTC is shipped with the rack mounting ears installed according to the customer configuration.

The type of screws used for this procedure vary depending on the rack type. Use the following screws supplied with the DTC packout, when mounting the DTC in an ETSI rack:

Pan Head, Philips, M6x16mm-long, black Zinc (UTStarcom P/N 500-0113-001) using 3.9 N-m (35 in-lbs) torque with a #2 Philips screwdriver

Use the following screws supplied with the DTC packout, when mounting the DTC in a 23-inch rack:

Combination Pan Head, Pilot Point, #12-24, 0.5 inch-long, black Zinc (Chatsworth P/N 40605; UTStarcom P/N 500-0112-001) using 3.9 N-m (35in-lbs) torque with a #3 Philips screwdriver

Step 1 Insert one temporary mounting position screw on each side of the rack to support the chassis (see Figure 3-8 on page 3-15). The location of this temporary screw is 5 inches above the bot-tom of the final position of thechassis for 23-inch rack and 5.5 mm above the bottom of the final position of the chassis for ETSI rack.

Step 2 Partially tighten the screws (approximately four turns).

Step 3 With two people, lift the chassis and slide the rear of the chassis into the desired location of the rack. Rest the mounting ears of the chassis on the two temporary screws inserted in the rack (see Figure 3-8 on page 3-15).


The chassis is a heavy object, and weighs about 75 lbs after removing the parts. It may require the service of two persons to lift and mount it on the rack.

Note: The Figure 3-8 on page 3-15 illustrates the 23-inch rack flush mount position.



Figure 3-8 Securing the Chassis to the rack

Step 4 Align the screw holes on the mounting ears with the screw holes on the sides of the rack.

Step 5 Insert rack mount screws into each mounting ear, starting at the bottom of the chassis (see Figure 3-9 on page 3-16).

Use 10 screws on each side for ETSI rack mounting.

Use eight screws on each side for 23-inch rack mounting.

To reinstall the DTC front door

Note: The DTC front door is not reinstalled if you have installed the DTC in an ETSI rack.

Step 1 Collect the stored front door which was removed from the chassis. Refer to “To remove the DTC front door” on page 3-11.

Step 2 Holding the top and bottom of the door with both hands, position the door at 900 to the chassis, near the hinges.

Step 3 Align the door hinges to the pins on the chassis.

Step 4 Slide the hinges onto the pins.

Step 5 Close the door with the front door latch on the right side.

Installing and Verifying the Ground CablingThe DTC has four grounding points, two at the rear of the chassis and two more toward the front side of the chassis.

Note: For ETSI flush mount and 23-inch flush mount positions, use the grounding points located at the rear of the chassis. For the 23-inch forward mount position, use the grounding points located toward the front of the chassis.

To connect the ground cable

UTStarcom recommends using green-colored ground cables to ground the DTC, and the following ground lug:

Panduit P/N LCD2-14A-Q, #2AWG, ¼” Bolt, 5/8” spacing

Note: Use only the supplied four grounding screws.

Step 1 Verify that the circuit breaker on the PEMs are OFF.

Step 2 Run two ground cables (one cable at a time) from the rack to the grounding points on the right and left rear of the DTC (see Figure 3-10 on page 3-19).

Step 3 Cut four 2-inch lengths of 1/2-inch heat shrink tubing (clear tubing is recommended).

Step 4 Place a 2-inch length of heat shrink tubing over each end of the cables.

Step 5 Using a wire stripper, strip and prepare both ends of the grounding cables to accept a compres-sion type terminal lug.



Note: The lugs must be UL/CSA approved.

Step 6 Using a Panduit P/N CT-1700 wire crimping tool, crimp a terminal lug on each end of the ground-ing cables.

Step 7 Slide the heat shrink tubing back over the compression lug for each ground cable.

Step 8 Using a heat gun, shrink each sleeve.

Step 9 Connect one end of the grounding cable to the rack and secure it with a rack mount screw using a #3 Philips screwdriver to the recommended torque (35 in-lbs).

Step 10 Connect the other end of the grounding cable to the grounding point on the rear of the chassis and tighten the screws (1/4-20x0.5” Zinc SEM screw, UTStarcom P/N 500-0038-001), using #3 Philips screwdriver to the recommended torque (40 in-lbs).

Step 11 Remove the slack on the grounding cable by tying it to the rack.

Step 12 Turn on the multimeter and select the lowest (100 ohm or Rx1) resistance range.

Step 13 Touch the leads of the meter together to ensure that the meter is working properly. The meter should read 0.0ohms.

Step 14 Connect one probe of the multimeter to a grounded cable lug on the rear of the DTC.

Step 15 Connect the other probe of the multimeter to another point on the chassis.

Step 16 Read the multimeter display; the reading must be 0.0 or less than 0.1 ohm. A resistance greater than 0.1 ohm indicates an improperly grounded system and additional troubleshooting must be performed to correct the problem.

Step 2 If no other cabling is required, reinstall the front top cover as described in “To reinstall the front top cover” on page 3-16.

Connecting and Routing FibersAlways clean and label fiber optic cables before use, and observe the safety precautions outlined in “Laser Safety” on page 1-7.

CAUTIONRisk of exposure to invisible radiation.Do not view the fibers and optical connectors directly with optical instruments. Class 1 and Class 1M radiation present.

To connect and route optical fibers, take the following steps:

Connect DLM tributary port fiber optic cables. (See “To connect the DLM tributary port fiber optic cables” on page 3-47.)

Connect Optical Carrier Group (OCG) port fiber optic cables between the DLMs and BMMs. (See “To connect OCG cables between the DLMs and BMMs” on page 3-48.)

Route OCG and tributary port fiber optic cables. (See “To route the OCG and tributary port fiber optic cables” on page 3-49.)

Connect BMM line side fiber optic cables.

See “To connect line side fiber cables to the TN780” on page 3-51 for connecting line side fibers from any network element to the TN780.

See “To connect line side fiber cables between two TN780s” on page 3-52 for connecting the TN780 to another TN780.

See “To connect line side fiber cables from the TN780 to an Optical Line Amplifier” on page 3-52 for connecting the TN780 to an Optical Line Amplifier.

Note: Optical fiber cables are also used to interconnect the DTC and DMC. For more information, see “Interconnecting the DTC and DMC” on page 3-53.

To connect the DLM tributary port fiber optic cables

Step 1 If the DTC front door is closed, follow the procedure “To remove the DTC front door” on page 3-11.

Step 2 Ensure the tributary optical fibers are clean and labeled.

Step 3 Insert a pair of clean, labeled fiber optic cables into the upper (IN) and lower (OUT) connectors in each TOM on the DLM (see Figure 3-24 on page 3-48).

Step 3a Connect incoming tributary fibers to the IN ports.

Step 3b Connect outgoing tributary fibers to the OUT ports.

Step 4 Repeat step 2 for each installed DLM.

Note: Fiber optic cables have straight or curved boots for routing the fiber to the fiber guide. Curved boots are recommended for use. Straight boots are also supported.



Figure 3-24 Connecting the fiber optic cables to the TOM

To connect OCG cables between the DLMs and BMMs

Each BMM circuit pack supports four OCGs (OCG 1, OCG 3, OCG 5 and OCG 7). There are four DLM circuit packs, one for each OCG. Ensure that the OCG port on the DLM circuit pack is connected to the corresponding OCG port on the BMM (see Table 3-5 on page 3-48).

Step 1 Ensure the optical fibers are clean and labeled.

Step 2 If the DTC front door is closed, follow the procedure “To remove the DTC front door” on page 3-11.

Step 3 Connect the OCG port on a DLM to the corresponding OCG port on the BMM with the optical fibers, using the port association specified in Table 3-5 on page 3-48. For a given OCG, be sure to connect the OUT DLM OCG port to the IN BMM OCG port, and the IN DLM OCG port to the OUT BMM OCG port.

To route the OCG and tributary port fiber optic cables

The DLM OCG and tributary fiber optic cables are routed through the DLM fiber guide to the fiber trays.

Step 1 Route the DLM OCG port and tributary fiber optic cables connected to the TOM ports on the TAM in slot 1 through 4 through the DLM fiber guide (see Figure 3-26 on page 3-50).

Step 1a The fibers from the TAM in slot 1 are routed through the fiber guide cable holders closest to the faceplate, in stair stepped routing.

Step 1b The fibers from the TAM in slot 2 are routed through the fiber guide cable holders in the 2nd column closest to the faceplate, in stair stepped routing.

Step 1c The fibers from the TAM in slot 3 are routed through the fiber guide cable holders in the 3rd column closest to the faceplate, in stair stepped routing.

Step 1d The fibers from the TAM in slot 4 are routed through the fiber guide cable holders in the 4th column closest to the faceplate, in stair stepped routing.

Step 1e The fibers from the TAM in slot 5 are routed directly through the fiber guide tray.

To connect line side fiber cables between two TN780s

Each TN780 may contain up to two BMMs. It is recommended that a node numbering scheme be established for the network. For example, eastbound traffic BMM numbering is from BMM1 (Node A) to BMM2 (Node B) and westbound traffic is from BMM2 (Node B) to BMM1 (Node A).


Step 2 Connect line fibers from the OUT (transmit) line port on BMM1 (Node A) to the IN (receive) line port on BMM2 (Node B) for eastbound traffic.

Step 3 Connect line fibers from the OUT (transmit) line port on BMM2 to the IN (receive) line port on BMM1 for westbound traffic.


Now Nodes A and B are connected and you have created an optical link.

To connect line side fiber cables from the TN780 to an Optical Line Amplifier

Each TN780 may contain up to two BMMs and each Optical Line Amplifier may contain up to two OAMs. It is recommended that a node numbering scheme be established for the network. For example, eastbound traffic numbering is from OAM1 (Node A) to BMM1 (Node 2) and westbound traffic is from BMM2 (Node B) to OAM2 (Node A).


Step 1 Connect line fibers from the OUT (transmit) Line Port on BMM1 (Node A) to the IN (receive) line port on OAM1 (Node B) for eastbound traffic.

Step 2 Connect line fibers from the OUT (transmit) line port on OAM2 to the IN (receive) line port on BMM1 for westbound traffic.


Now Nodes A and B are connected and you have created an optical link.



Interconnecting the DTC and DMCThe DTCs connects to the DMC through fiber optic cables. The DMC is housed in the same rack with the DTC. Refer to CHAPTER 5, “Installing the Dispersion Management Chassis” on page 5-1 for the procedure.

The fiber cables are connected to the DCM IN and DCM OUT ports of the BMM. The cables are routed as illustrated in Figure 3-28 on page 3-53, and are connected to the ports of Dispersion Compensation Module in the DMC.

Figure 3-28 Fiber optic cables between DTC and DMC

If installing only a single-chassis system, the TN780 system is now ready for startup and test. Refer to the UTStarcom TN780 Turn-up and Test Guide for the more information.

Page 3-54 Installing a Multi-chassis SystemPage 3-54

Installing a Multi-chassis SystemTo physically install a multi-chassis system, take the following steps:

Step 1 Install each DTC separately. Use the same procedures documented in “Installing the DTC” on page 3-10, noting the exception discussed below in “Installing Multi-chassis OCG Cables” on page 3-54.

Step 2 Install the multi-chassis NCT cables. See “Installing Multi-chassis NCT Cables” on page 3-54.

Step 3 Proceed to the UTStarcom TN780 Turn-up and Test Guide for multi-chassis system startup and test.

Installing Multi-chassis OCG CablesWhen connecting OCG ports between BMMs and DLMs on a multi-chassis system, note that the interconnected BMMs and DLMs may reside on different chassis, depending on the network topology. (See UTStarcom TN780 System Description for a description of the various digital optical network topologies.) In other words, OCG fiber cables may connect DLMs on one chassis to a BMM on another chassis.

Installing Multi-chassis NCT CablesIn a multi-chassis configuration, chassis are interconnected at the nodal control and timing (NCT) ports of their IO panels using unshielded twisted pair CAT5 Ethernet cables that conform to 100BaseTX (IEEE 802.3) specifications, with male RJ-45 connectors at both ends. The maximum length allowed for each NCT cable segment between chassis is 100 meters (328 feet).

The Main Chassis cannot be pre-provisioned, and must be provisioned during network element turn-up. Expansion chassis may be pre-provisioned. The physical connection of NCT cables may be made prior to provisioning the chassis, or after pre-provisioning the chassis. For complete information about multi-chassis configuration, see the UTStarcom TN780 Turn-up and Test Guide.

Release 1.2 certifies a dual-chassis configuration between DTCs. Although there are many ways to interconnect multiple chassis, the following recommended configurations provide the greatest level of redundancy, capacity, and management/control plane availability:

Cabling dual chassis for fully redundant MCMs (See “To connect NCT cables for fully redundant chassis” on page 3-55.)

Cabling dual chassis for non-redundant MCMs (See “To connect NCT cables for non-redundant chassis” on page 3-55.)

Cabling dual chassis for MCM redundancy only on the Main Chassis (See “To connect NCT cables for Main Chassis redundancy” on page 3-56.)



To connect NCT cables for fully redundant chassis

In the instructions below, the following convention is used to specify NCT ports on a particular chassis: [ChassisID]-NCT-[PortNumber][A|B]. For example, NCT port 2A on chassis 1 is specified as 1-NCT-2A.

Step 1 Connect 1-NCT-2B to 2-NCT-1A.

Step 2 Connect 1-NCT-2A to 2-NCT-1B.

Step 3 Connect 2-NCT-2B to 1-NCT-1A.

Step 4 Connect 2-NCT-2A to 1-NCT-1B. The final logical connectivity is illustrated below in Figure 3-29.

Figure 3-29 NCT connectivity for dual-chassis with full MCM redundancy

To connect NCT cables for non-redundant chassis

In the instructions below, the following convention is used to specify NCT ports on a particular chassis: [ChassisID]-NCT-[PortNumber][x|y], where the variable x is the MCM subslot identifier for chassis 1 (that is, either A or B, depending on whether the MCM is housed in slot 7A or 7B), and y is the MCM subslot identifier (either A or B) for chassis 2.

Step 1 Connect 1-NCT-1x to 2-NCT-2y. For example, if the chassis 1 houses its MCM in slot 7A, and chassis 2 houses its MCM in slot 7B, connect NCT port 1A on the chassis 1 to NCT port 2B on chassis 2.

Step 2 Connect 2-NCT-2y to 1-NCT-1x. The final logical connectivity is illustrated below in Figure 3-30.



Figure 3-30 NCT connectivity for a non-redundant dual-chassis configuration

To connect NCT cables for Main Chassis redundancy

In the instructions below, the following convention is used to specify NCT ports on a particular chassis: [ChassisID]-NCT-[PortNumber][A|B|y]. The variable y is the MCM subslot identifier for the Expansion Chassis. It has the value A or B, depending on whether the MCM resides in slot 7A or 7B of the Expansion Chassis.

Step 1 Connect Main-NCT-2B to Expansion-NCT-1y. For example, if the Expansion Chassis houses its MCM in slot 7A, connect NCT port 2B on the Main Chassis to NCT Port 1A on the Expansion Chassis.

Step 2 Connect Expansion-NCT-2y to Main-NCT-1A. The final logical connectivity is illustrated below in Figure 3-31.



Figure 3-31 NCT connectivity for MCM redundancy only on Main Chassis

If you choose to use some other NCT cabling configuration, be sure the topological connectivity is consistent with the following datapath communication guidelines:

External Management Communication — External management interfaces always communicate to the active MCM on the Main Chassis through the DCN port of its I/O panel. If an MCM is not avail-able on the Main Chassis, then the entire network element is not reachable. This is true even if there are in-service MCMs present on the Expansion Chassis. If both DCNs on the Main Chassis are con-nected to the operations support system (OSS), then failure of an active card that results in a switch to standby will be carried out transparently on the other DCN.

Optical Supervisory Channel (OSC) to MCM Communication — OSC traffic always goes through the active MCM within the same chassis. The scope of OSC to MCM communication is lim-ited to the scope of the single chassis.

Inter-shelf MCM to MCM Communication — The active MCM on the Expansion Chassis commu-nicates with the active MCM on the Main Chassis and vice-versa (provided that NCT connectivity is properly configured). Therefore, if no MCM is present on an Expansion Chassis, or the MCMs on the Expansion Chassis are present but faulted, then that Expansion Chassis is not reachable by the Main Chassis.

Intra-shelf MCM to Line-card Communication — The scope of line-card (DLM or BMM) to MCM communication is limited to the scope of the single chassis. In other words, line-cards always com-municate to the active MCM on the same chassis. Therefore, if no MCM is present on the Expansion Chassis, or the MCMs on the Expansion Chassis are present but faulted, then any alarms or perfor-mance monitoring data for the line-cards cannot be sent automatically to the management inter-faces.



Note: When the multi-chassis system is deployed, the data communication network (DCN) on only the Main Chassis is active. The DCN on the Expansion Chassis is disabled.

Installing and Verifying the Ground Cabling The OTC has two grounding points at the rear of the chassis.

To connect the ground cable

UTStarcom recommends using green-colored ground cables to ground the OTC, and the following ground lug:

Panduit P/N LCD2-14A-Q, #2AWG, ¼” Bolt, 5/8” spacing

MountingScrews



Note: Use only the supplied four grounding screws.

Step 1 Verify that the circuit breaker on the Power Distribution Unit (PDU) are OFF.

Step 2 Run two ground cables (one cable at a time) from the rack to the grounding points on the right and left rear of the OTC (see Figure 4-8 on page 4-12).


Step 4 Slide the 2-inch lengths of heat shrink tubing onto each cable, moving it along the cable until the cable end is exposed.

Step 5 Using a wire stripper, strip and prepare both ends of the grounding cables to accept a compres-sion type terminal lug.

Note: The lugs must be UL/CSA approved.

Step 6 Using a Panduit P/N CT-1700 wire crimping tool, crimp a terminal lug on each end of the ground-ing cables.

Step 7 Slide the heat shrink tubing back over the compression lug for each power cable.


Step 9 Connect one end of the grounding cable to the rack and secure it with a rack mount screw using a #3 Philips screwdriver to the recommended torque (35 in-lbs).

Step 10 Secure the grounding cable to the chassis using 4 screws.

Step 11 Connect the other end of the grounding cable to the grounding point on the rear of the chassis and tighten the screws (1/4-20x0.5” Zinc SEM screw, UTStarcom P/N 500-0038-001), using #3 Philips screwdriver to the recommended torque (40 in-lbs).

Step 12 Remove the slack on the grounding cable by tying it to the rack.

Step 13 Turn on the multimeter and select the lowest (100 ohm or Rx1) resistance range.

Step 14 Touch the leads of the meter together to ensure that the meter is working properly. The meter should read 0.0 ohms.

Step 15 Connect one probe of the multimeter to a grounded cable lug on the rear of the OTC.

Step 16 Connect the other probe of the multimeter to another point on the chassis.

Step 17 Read the multimeter display; the reading must be 0.0 or less than 0.1ohm. A resistance greater than 0.1ohm indicates an improperly grounded system and additional troubleshooting must be performed to correct the problem.

a. When there is no power fault condition, the Normally Open contact is closed and the Normally Close contact is open. When both PEM A and PEM B have power fault condition, the Normally Open contact is open and Normally Close con-tact is closed. The power fault is defined as when the power input into PEM A or PEM B is out of working range.






Note: Fiber optic cables are also used to interconnect the OTC and the DMC. For more informa-tion, see “Interconnecting OTC and DMC” on page 4-31.

To connect and route the OAM fiber optic cables

To provide line amplification for signals going from West to East, the Line IN port on a given OAM is connected to the incoming fiber from one direction (e.g. West) while the Line OUT port on the same OAM is connected to the outgoing fiber in the opposite direction (e.g. East). As a result, the receiver on the OAM receives from one direction and the transmitter on the same OAM transmits towards the opposite direction. The fiber optic cables are routed through the fiber guide.

Step 1 Insert a pair of clean, labeled fiber optic cables into the connectors in each OAM (see Figure 4-15 on page 4-29 for the physical insertion of the cables, and Figure 4-16 on page 4-30 for the logical connection of the fibers).

Step 2 Route the cables forward top right side through the fiber guide.

Step 3 Secure the cable pairs using tie-downs or wrap extra fiber around a slack manager. The OTC supports optional slack management ears, UTStarcom P/N O-FIBMGMT-B1.

Note: Fiber optic cables have straight or curved boots for routing the fiber to the fiber guide. Curved boots are recommended for use. Straight boots are also supported.

Figure 4-16 Logically connecting the fiber optic cables

To connect the OSC jumper

The OSC jumper transmits OSC signals between OAMs in a bidirectional Optical Line Amplifier. With this configuration, an OAM failure would impact the OSC in one direction only, and the node would still be accessible. To connect the OSC jumper, take the following steps:

Step 1 Using the OSC optical patch cord (SC to SC fiber cable, shipped with the OAM), connect the OSC OUT port on the first OAM to the OSC IN port on the second OAM. See Figure 4-16 on page 4-30.

Step 2 Using another OSC optical patch cord, connect the OSC IN port on the first OAM to the OSC OUT port on the second OAM.



Interconnecting OTC and DMCThe OTC connects to the DMC through fiber optic cables. The DMC is housed in the same rack with the OTC. Refer to CHAPTER 5, “Installing the Dispersion Management Chassis” on page 5-1 for installation procedures.

The fiber cables are connected to the DCM IN and DCM OUT ports of the OAM. The cables are routed as illustrated in Figure 4-17 on page 4-31 below and are connected to the ports of Dispersion Compensation Module in the DMC.

Note: Refer to “To install the rack mounting ears on the chassis” on page 5-6 for rack mounting positions.

The rack mounting screws are supplied with the DMC packout for mounting the DMC on the rack. These screws are different for ETSI and 23-inch racks.

Use the following screw to mount the DMC in an ETSI rack:


Use the following screw to mount the DMC in a 23-inch rack:

Combination Pan Head, Pilot Point, #12-24, 0.5inch-long, black Zinc (Chatsworth P/N 40605; UTStarcom P/N 500-0112-001) using 3.9 N-m (35 in-lbs) torque with a #3 Philips screwdriver

Step 1 Lift the chassis and slide the rear of the chassis into the desired location of the rack (see Figure 5-4 on page 5-7).

Step 2 Align the two screw holes on the rack mounting ears with the screw holes on the sides of the rack.

Step 3 Insert two rack mount screws into each mounting ear, starting at the bottom of the chassis.

Step 4 Ensure that the chassis is having two mounting screws on each side.

Step 5 Tighten the screws with a #3 Philips screwdriver using 35in-lbs torque.

Installing DCMsOnce you have installed the chassis in the rack, you are ready to install the DCM in the chassis. The DCMs are of half-width and full-width types. The type and quantity of DCMs depends on the specific configuration of the DMC (refer to your packing slip). To install the DCMs, follow the instructions provided below:

To install a half-width DCM, see “To install a half-width DCM” on page 5-8.

To install a full-width DCM, see “To install a full-width DCM” on page 5-9.

To install a half-width DCM

See Figure 5-5 on page 5-9 for mounting position of the half-width DCM in the chassis.

Step 1 Swing the thumb screw receiver plates on the DMC completely toward the outside of the chas-sis.

Step 2 Ensure that the plate does not interfere with the path for the DCM.

Step 3 Slide the DCM into the chassis.

Step 4 Align the side edge of the DCM base plate with the side wall of the chassis.

Step 5 Ensure that the faceplate and the thumb screws face outward from the chassis. Deployment of the DCM on the left or right side of the chassis depends on the customer preference.

Step 6 Continue to slide the DCM into the chassis until the fiber guides on the base plate are past the lip of the chassis. Do not push the DCM all the way into the chassis.

Step 7 Swing the thumb screw receiver plate in toward the DCM until it stops. This plate should be par-allel to the face plate, and the screw hole should line up with the thumb screw.

Step 8 Slide the DCM the rest of the way into the chassis straight and under the tab. The top cover of the chassis may have to be lifted slightly to allow the face plate to slide underneath. The face plate should be flush with the top cover of the chassis.

Step 9 If the DCM is not slid into the chassis straight, pull the DCM out slightly and then re-insert it closer to the side wall of the chassis.

Step 10 Verify that the base plate of the DCM has been placed under the tab in the back inside of the chassis.

Step 11 Tighten the thumb screw that aligns with the thumb screw receiver. The second thumb screw on the small DCM, in the center of the chassis, will not be used.

Step 12 Repeat steps 1 through 11 for the second slot in the chassis.



Figure 5-5 Inserting a half-width DCM

To install a full-width DCM

See Figure 5-1 on page 5-3 for mounting position of the full-width DCM in the chassis.

Step 1 Swing the two thumb screw receiver plates completely behind the faceplate.

Step 2 Ensure that the plate does not interfere with the path for the DCM.

Step 3 Slide the DCM into the chassis.

Step 4 Align the side edge of the DCM base plate with the side wall of the chassis.

Step 5 Ensure that the faceplate and the thumb screws face outward from the chassis.

Step 6 Continue to slide the DCM into the rack until the fiber guides on the base plate are past the lip of the chassis. Do not push the DCM all the way into the chassis.

Step 7 Verify that the thumb screw receiver plates are parallel to the face plate. The screw hole should line up with the thumb screw.

Step 8 Slide the DCM the rest of the way into the chassis straight and under the tab. The top cover of the chassis may have to be lifted slightly to allow the face plate to slide underneath. The face plate should be flush with the top cover of the chassis.

Step 9 If the DCM is not slid into the chassis straight, pull the DCM out slightly and then re-insert it closer to the side wall of the chassis.

Step 10 Verify that the base plate of the DCM has been placed under the tab on the right inside of the chassis.

Step 11 Tighten the thumb screws on both the sides of DCM that aligns with the thumb screw receiver.

Connecting and Routing Fibers

To connect the fiber optic cables

Step 1 Insert a pair of clean fiber optic cables into the connectors in each of the DCMs (see Figure 5-6 on page 5-10).

Step 2 Route the cables neatly as shown in the figure.

Step 3 Secure the cable pairs using tie-downs.
