2Introduction to OMUAbout This Chapter

The physical entity of the OMU is the OMUa board. The OMUa board collects and processes

the information about operation and maintenance (OM), and then reports the information to the

OM terminal: LMT or M2000.

2.1 Position of the OMU in the BSC6900

This describes the components of the BSC6900 OM subsystem and the position of the OMU in

the OM subsystem.

2.2 OMUa/OMUb Board

OMUa refersto Operation and Maintenance Unit REV:a. OMUb refers to Operation and

Maintenance Unit REV:b. One or two OMUa/OMUb boards must be configured in the

BSC6900. The width of the OMUa/OMUb board is twice the width of other boards. Therefore,

one OMUa/OMUb board occupies twoslots. The board can be installed in slots 0 to 3, slots 20

to 23, or slots 24 to 27 in the MPS. Slots 24 to 27 are recommended.

2.1 Position of the OMU in the BSC6900

This describes the components of the BSC6900 OM subsystem and the position of the OMU in

the OM subsystem.

The BSC6900 OM subsystem is composed of the LMT/M2000, OMUa/OMUb board or

GBAM (OMU), SCUa board, and OM modules on other boards. In the BSC6900 OM subsystem,

the OM terminal (LMT or M2000) communicates with the BSC6900 host boards through the

OMU.

Figure 2-1shows the position of the OMU in the BSC6900 OM subsystem.

Figure 2-1Position of the OMU in the BSC6900 OM Subsystem

NOTE

Figure 2-1takes the OMUa board as an example. Both the OMUb board and GBAM can replace the OMUa

2.3.6 Replacing the GBAM

This section describes how to replace a faulty GBAM. It takes about 40 minutes to replace a

GBAM. There are three models of GBAM, namely, IBM X3650T, C5210, and HP CC3310.

Prerequisite

l The tools are ready. They are the ESD wrist strap, Phillips screwdriver, straight screwdriver,

and ESD boxes or bags.

l A new GBAM is ready.

CAUTION

l When configuring the new GBAM or OMU board, ensure that the following parameter

settings are consistent with those of the GBAM to be replaced: server name or computer

name, OS administrator password, admin password, and IP address.

l If you change the IP address of the GBAM, you need to reset the alarm box manually.

Context

CAUTION

To avoid damage to the boards, ASIC chips, or other electronic components, wear an ESD wrist

strap properly. Ensure that the ESD wrist strap is properly connected to the ESD connector on

the cabinet. If no ESD wrist strap or no proper grounding point is available, wear ESD gloves.

CAUTION

l Replacing the GBAM disrupts the communication between the GBAM and the host boards.

l Replacing the GBAM disrupts the communication between the LMT/M2000 and theBSC6900. In this case, you cannot maintain the BSC6900 or collect the alarm information.

The BSC6900 host boards, however, work normally during thereplacement of the GBAM.

Procedure

l Replace the GBAM with a new GBAM.

1. Log in to the GBAM as user root, and then run the Linux OS command /etc/rc.d/

omud stopto stop all applications on the GBAM to be replaced.

2. Run the Linux OS command poweroffto shut down the GBAM to be replaced.

3. Turn off SW3 and SW6 on the power distribution box that control the power supplyto the GBAM to be replaced. Figure 2-14shows the labels for the power switches on

the front panel of the power distribution box.

4. Check whether the labels on the cables that are connected to the GBAM to be replaced

are legible. If the labels are not legible, attach a new label to the cables to avoid

improper connection after replacing the GBAM.

5. Remove the power cable, PGND cable, and Ethernet cables from the GBAM to be

replaced.

6. Remove the screws fixing the GBAM to the rack.

7. Remove the hangers from the GBAM to be replaced, and then install the hangers on

the new GBAM.

8. Remove the GBAM from the cabinet along the guide rails.

9. Place the new GBAM in the original position. Then, secure the screws.

10. Connect the power cable, PGND cable, and Ethernet cables to the new GBAM.

11. Turn on the power switch controlling the power supply to the GBAM on the power

distribution box. For distribution of the power switches, see labels on the front panelof the power distribution box, as shown in Figure 2-14.

CAUTION

l Do not perform any operations that will modify the configuration data or the attributes

when replacing the GBAM.l Get a PC ready for file backup during the GBAM replacement.

1. The OMU board can be installed in slots 0 to 3, 20 to 23, or 24 to 27 in the MPS. When

replacing the GBAM with the OMU board, first run the LST BRDcommand to check

whether there is an idle slot for the OMU board. If there is no idle slot for the OMU

board, first modify the configuration data.

2. Collect the required information.

(1) Run the DSP OMUcommand to obtain the computer name and external fixed

IP address of the GBAM.

NOTE

If the external fixed IP address is not configured, its value is displayed as null. In this case,

one must apply for an IP address that is in the same network segment as the external virtual

IP address and use it as the external fixed IP address.

(2) Run the LST VERcommand to obtain the version information about the GBAM.

(3) Run the Linux OS command routeto obtain the external mask and gateway IP

address of the GBAM.

(4) Run the Linux OS command ps -afxto obtain the common directory and active

workspace directory of the OMU.

3. Obtain the version software based on the version information obtained in step 2.2.

4. Back up the data on the GBAM.

(1) Create a backup directory on the hard disk that has at least 1 GB free space on

the PC. The backup directory is used to back up the data on the GBAM. Then,

create subdirectories common, data, license, DefaultMeas, cert, and bin under

the backup directory.

(2) Back up the reg.ini file in the common directory of the OMU to the backup/

common directory of the PC.

(3) Run the BKP DBcommand to back up the OMU databases. The backup

databases are stored in /data/backup of the OMU active workspacedirectory.

Then, back up the files in /data/backup of the OMU active workspacedirectory

to the backup/data directory of the PC.(4) Back up the license files in the license of the OMU active workspacedirectory

to the backup/license directory of the PC.

(5) Back up the performance task files in /ftp/DefaultMeas of the OMU active

workspacedirectory to the backup/DefaultMeas directory of the PC.

(6) Back up the certificate files in /ftp/cert of the OMU active workspacedirectory

to the backup/cert directory of the PC.

(7) Back up the bin directory. To back up the bin directory, first run the Linux OS

command tar czvf bin.tgz bin/in the OMU active workspacedirectory to

compress the bin directory. Then, back up the compressed bin.tgz file to the

backup/bin directory of the PC.

5. Shut down the GBAM to be replaced.
