1.8.12 Install the OMS 870 Fiber Cable



To install fiber-optic cables in the OMS 870, connect a fiber cable with LC connector type to the transmit and receive ports of the transmission system. On a the OMS 870 module, the transmit and receive ports are located at the back of the module. The receive port is named IN and the transmit port is named OUT.

Ericsson recommends that you label the transmit and receive fiber to and from the optical transmission system at each end of the fiber span to avoid confusion with cables that are similar in appearance.

Warning!

Follow all directions and warning labels when working with optical fibers. To prevent eye damage, never look directly into a fiber or connector.

Connect the Fiber Cable

1. Remove the dust plugs from the LC (STM-n) connectors.

2. Clean and inspect the LC jumper cable connectors.

3. Connect the LC module input and output to the customer-specified point.

1.8.13 Install the OMS 870 Electrical Cable



To install electrical-connection cables in the OMS 870, connect an electrical cable to the corresponding ports of the transmission system. On the OMS 870 module, the electrical ports are located at the back of the module.

All electrical cables are equipped with RJ-45 connectors. The alarm cable is equipped with a 9 pin D-Sub connector. Ericsson recommends that you label the electrical cable at each end to avoid confusion with cables that are similar in appearance.

Warning!

Follow all directions and warning labels when working with electrical cables.

Connect the Electrical Cables with RJ-45 Connector

1. Carefully connect the electrical cables with RJ-45 connectors to the customer-specified point.

2. Repeat Step 1 for all other electrical cables.

3. Guide the cables through the cable ties mounted on the sides of the rack. The cable ties hold the cables to the side of the rack to reduce the risk of fiber pinching.

1/1531-CRA 119 0513/30 Uen A 2007-11-15 1-24


Connect the Alarm Cable

1. Carefully connect the alarm cable to the alarm port.

2. Fix the connector with the retaining screw to the alarm port.

3. Guide the cable through the cable ties mounted on the sides of the rack. The cable ties hold the cables to the side of the rack to reduce the risk of fiber pinching.

1.8.14 LFH cables

Special cables with Molex LFH connectors for the high-density modules are provided for connection between the OMS 870 and a patch-panel.

Warning!

To protect the cable jacket, avoid sharp edges and excessive bending. Always fasten the cable connectors with both fixing screws. If the connector is fixed with one screw only, this screw is likely to break if the cable is pulled by accident.

1.9 SFP Modules

1.9.1 Introduction

The SFP modules to be used together with the 2xGE-2xSMAP-SFP and 8xFE-SFP service modules are available from Ericsson. The following SPFs are currently approved by Ericsson:

• Sumitomo, SCP6844-GL-AWH

• Delta, LCP-1250B4QSM

• Delta, LCP-1250A4FSM

• Finisar, FTRJ1319P1BTL

• Finisar, FTRJ8519P1BNL

1.9.1.1 S-1e SFPs in OMS 870At the moment, in general two S-1e suppliers are qualified to be used in the OMS 870:

• Teridian (former TDK)

• ITT/AimBridges.

Due to the tight solution with the 2x4 ganged SFP cage, only ITT/AimBridges SFPs can be used in the OMS 870 TM 8xSTM-1 SFP.

The Teridian SFP body outside the cage is too big, and is mechanically not compatible with the MSA specification. A ganged side-by-side installation is not possible.

Special slim 1.0/2.3 coaxial cable connectors are required to interface the S-1e SFPs in the OMS 870 TM 8xSTM-1 SFP. ITT Cannon and Compel are possible sources for these connectors.

1.9.2 DISCLAIMER

If using other SFP modules than delivered from Ericsson, Ericsson disclaim responsibility of possible damage or malfunction that might

1/1531-CRA 119 0513/30 Uen A 2007-11-15 1-26


occur to involved equipment. Ericsson may also introduce coded SFPs in the future, which will complicate a SW upgrade

1.9.3 Installation of SFP Modules

This section provides instructions for installing, connecting, and removing SFP modules.



Warning!

Fiber-optic SFP modules are equipped with a Class 1 laser, which emits invisible radiation. Do not stare into open optical ports.

Fiber-Optic SFP modulesSome fiber-optic SFP modules use LC-type connectors, as shown in Figure 10

1-271/1531-CRA 119 0513/30 Uen A 2007-11-15


Caution! Insert clean dust plugs into the SFP module after removing the

cables to protect the fiber-optic. Clean the optic surfaces of the fiber-optic cables with a soft antistatic cloth before you reconnect them to another SFP module. Take actions to avoid dust and other contaminants getting into the optical apertures. Optics fail when obstructed with dust.

Figure 10 LC Fiber-Optic SFP module

1.9.4 Installing and removing SFP modules

The latching device secure and detach the SFP module from a port. SFP modules can be equipped with different types of latching devices:

• Pull tab latch

• Actuator button latch

• Bale-clasp latch is depicted in Figure 11

Caution! Do not install or remove the SFP module with fiber-optic cables

attached to it, due to the potential damage to the cables, the cable connector, or the optical interfaces in the SFP module. Disconnect all cables before removing or installing an SFP module. Do not remove and insert SFP modules more often than is absolutely necessary.

1/1531-CRA 119 0513/30 Uen A 2007-11-15 1-28


Figure 11 SFP Module with a Bale-Clasp Latch

1.9.4.1 Installing SFP modulesTo insert an SFP module into the SFP module slot, follow these steps:

1. Locate the send (TX) and receive (RX) markings that identify the top side of the SFP module.

N O T E ! On some SFP modules, the TX and RX can be marked as arrowheads, pointing from the SFP module connector (transmit direction /TX) and toward the connector (receive direction /RX).

2. Align the SFP module in front of the slot opening.

Make sure that the SFP module has the correct orientation, either a latch-up or a latch-down orientation.

3. Insert the SFP module into the slot. Insertion is correct when you feel the module-connector snap into place in the rear of the slot.

4. Remove the dust plugs from the optical ports on fiber-optic SFP modules and store them for later use.

N O T E ! When you are ready to connect the cable, remove the dust plugs from the fiber-optic SFP module port and the rubber caps from the fiber-optic cable. The plugs and caps protect the SFP module ports and cables from contamination and ambient light.

1.9.5 Removing SFP modules

To remove an SFP module from a module slot, follow these steps:

1. Disconnect the cable from the SFP module.

T I P Note which connector plug is send (TX) and which is receive (RX) in case you re attach the of fiber-optic cables.

1/1531-CRA 119 0513/30 Uen A 2007-11-15 1-30


2. Insert a dust plug into the optical ports of fiber-optic SFP modules.

3. Pull the bale out and down to eject the module.

Figure 13 Bale-Clasp Latch

If the bale-clasp latch is obstructed and you cannot use your index finger to open it, use a small, flat-blade screwdriver or other long, narrow instrument to open the latch.

4. Grasp the SFP module and carefully remove it from the module slot.

5. Store removed SFP module in an antistatic bag or other protective environment.

1.9.5.1 Connecting to SFP modulesFollow these steps to connect a fiber-optic cable to an SFP module:

1. Remove the rubber plugs from the module port and fiber-optic cable, and store them for future use.

2. Insert one end of the fiber-optic cable into the SFP module port (see Figure 14 )

2 Configuration of OMS 870 22.1 Initial configuration

2.1.1 Commissioning of IP address via VT100 Interface

2.1.1.1 Brief DescriptionA local terminal with VT100 emulation is required during the first commissioning of the network element in order to set up the necessary communications parameters enabling access to the element via AXX 9820 CRAFT over the Management Port. After the first commissioning, a VT100 interface can be used for modifying the communications parameters and perform some status checks of the network element. The VT100 interface is password protected.

Commissioning of IP address via a VT100 Interface CLI is a line-oriented ASCII-based management interface embedded in the network element.The CLI is accessed via the VT100-port. The serial connection communications parameters are fixed:

• 19200 bit/s,

• no parity,

• 8 bits,

• 1 stop bit,

• and no hardware flow control.

VT100 terminal codes are used. Default Telnet password is telnet.

The VT100-port (Console port) for the network element is provided using a RJ-45 connector. The cable for connecting the VT100-port to the serial-port on the PC can be provided. The specification of this cable is the following:

Figure 15 VT100-CABLE (Console cable)

1/1531-CRA 119 0513/30 Uen A 2007-11-15


N O T E ! Pin 4,5 and 7 are only used for debug purposes.

1. Connect the VT100 interface of the network element to a free COM port of the PC running the VT-100 application.

2.1.1.2 Invoke CLI

2. Enter COM port name and select OK.

3. An CLI session is invoked by typing omscli in terminal window. User authentication (password, 8-12 ASCII characters) is required, as the following session start-up sequence shows. Default password is omscli.

2.1.2 Configure User Management (UMA)

UMA is an extension to the basic SNMPv1 authentication and access control model. This extension consists of a client software process, a server software process residing in the target hardware and in the craft and/or element manager respectively. The application provides extended authentication and access control of SNMP clients.

Read more about UMA in the Marconi OMS 870 Technical Reference and the AXX 9820 CRAFT User guide.

It is possible to turn on or off the UMA function through the OMS Command Line Interface (OMSCLI) application.

OMSCLI>User-Management (UMA)\enable-user-managementUMA enabled

Per default UMA is on, and you can manage users with the AXX 9820 CRAFT. The default username is admin, with password admin.

It is also possible to manage UMA with OMSCLI:

Now you can log on to the NE with AXX 9820 CRAFT with the user testuser and the password testuser

2.1.3 Assign an IP-address to the OMS 870

The OMS 870 supports remote management solutions by means of Telnet and SNMP. The possibilities that regard to connectivity can be rather advanced for the OMS 870, so the only explained solution in this document is when directly connected the management-port (MNGT). For more information refer AXX 9820 CRAFT User Guide and Technical Reference Manual for OMS 870.

To achieve one of the above mentioned management solutions it is necessary to assign an IP-address, subnet-mask and if required, a default-gateway address must be defined.

2.1.3.1 System ModeFrom OMS 870 R2.0 on, an additional management mode, system mode, is added. System mode has two options IP and IPUNNUMBERED.

Prior to configuring the IP settings on the OMS 870 the desirable system mode should be set, since this is a strategic choice to align with the existing design of management data communication network. By default the system mode is IP, which means that all physical indices must have a unique IP address and subnet mask.

Warning!

Read instructions given in “IMPORTANT - System mode from IP to IP un-numbered” on page 2-40. Also see the AXX 9820 CRAFT User Guide.

2.2 Further configuration

2.2.1 IMPORTANT - System mode from IP to IP un-numbered

Products affected The IP un-numbered feature was introduced in OMS 870 Network Release (NR) 2.0. This field notice will apply for this and future releases.

Problem description Changing system mode from IP (default) to IP un-numbered may imply problems.

1/1531-CRA 119 0513/30 Uen A 2007-11-15 2-40


Problem symptoms Experiences from field (labs) tell us that current implementation have limitations in software for changing system mode from IP (default) to IP un-numbered.

Even though there are IP addresses and routing protocols configured on NE the operator does not receive any notification, which could have prevented the change until necessary configuration changes have been maintained.

From a software design point-of-view, the configuration of system mode for DCN routing is seen as a strategically choice, which the operator should configure prior to configure IP address and protocols on the device.

The reason for this is because the network design is different for each of the system modes.

The consequence for changing the system mode from IP to IP un-numbered is complicated and you may experience severe problems. Worst-case scenario is not being able to re-obtain IP connectivity to NE.

Workaround Generally the safest alternative is to erase the configuration prior to change the system mode. We are aware that this is an unpopular alternative, and have performed some testing to find a more proper workaround.

N O T E ! The following guidelines can not guarantee successful change from IP to IP un-numbered System mode. It is recommended that the configuration is tested on NE's in lab prior to perform the changes in a live environment.

Up till now we have tested some different configurations, and the following steps were successful:

1. Locally connect to MNGT-port and connect with AXX 9820 CRAFT.

2. Remove all IP addresses in the IP interface table except for the MNGT-port address (IF=1000).

3. Remove all static configured routes (even the 0.0.0.0 route).

4. Disable active routing protocols (RIP and/or OSPF).

5. Locally connect to device via CLI (VT100).

2-411/1531-CRA 119 0513/30 Uen A 2007-11-15


6. Remove IP address assigned to management port (CLI>ip ip=0.0.0.0 sub=0.0.0.0).

7. Set system mode to IP unnumbered (IPUN) and reset the device.

8. Change the IP address (MNGT-port) to fit your new network design and re-configure the SNMP community.

9. Re-connect to device with AXX 9820 CRAFT.

Commission IP un-numbered configuration. IP over PPP (DCC), OSPF, etc.
