Web LMT Introduction

The LMT provides graphical user interface (GUI) for you

to operate and maintain the BSC6900 on the Web page.

The alarm management, trace management, performance

monitoring, and device maintenance can be performed

through menu operations

The MML commands can be run for data configuration

and O&M on the LMT

Command Group

The BSC6900 system uses 32 command groups (G_0 to

G_31) to manage commands. Different command groups

can be assigned to different operators, so that they will

have different operation authorities.

Groups G_0 to G_14 are predefined by the system, the

contents cannot be changed

Groups G_15 to G_31 are initially null, the contents can be

defined.

Replacing a Board

There are two steps in replacing a BSC6900 board: Remove the

faulty board and insert the new board.

Prerequisites

The tools required for unfastening the board are available,

including ESD wrist strap, Phillips screwdriver, ESD box or ESD

bag, dustfree cloth, and fiber cleaner.

Background information

All the boards except the OMUa support hot swap.

Precautions

To avoid electrostatic damage, wear ESD wrist strap correctly

before replacing a board. If an ESD wrist strap is not available or

cannot be properly grounded, please wear ESD gloves.

Principles of replacing a board

Replacing an active or standby board

To replace an active board, run SWP BRD to switch over the

boards, pull out the now-standby board, and insert the new

board.

To replace a standby board, pull out the standby board and

insert the new board.

Replacing an independent board

This operation impacts the services and can cause service

interruption. To replace an independent board, transfer the

services of the board, run INH BRD to inhibit the board, pull

out the faulty board, and insert the new board.

) :18pt

Principles of replacing a board (Cont.)

Replacing a faulty board

If the faulty board is the DPU and only one or several DSPs

are faulty, inhibit the normal DSPs, and replace the faulty

board with a new one.

Verifying the board replacement

Run LST BRD to query the board inhibition status. If the

board is in "Inhibited" status, run UIN BRD to uninhibit the

board and observe whether the board works normally. If

not, check for alarms and analyze the problem according to

the alarm.

Page126


35pt

32pt

) :18pt

Replacing a DPUc/DPUd/DPUf /DPUg

Board Run the LST SUBRACK command to query the inhibited status of

the board.

If not inhibited, Run the INH BRD command to physically inhibit

the board.

Remove and insert the board.

Run the UIN BRD command to unblock the new board.

Run the DSP BRD command to query the status of the new board.

Check whether a board failure alarm is reported on the LMT.

Run the CMP BRDVER command to check whether the software

version of the new board is consistent with the board version

matching table.

) :18pt

Replacing OMU

A faulty OMU board needs to be replaced to prevent data from

being lost when OMU operation and maintenance are interrupted

due to disconnection between the OMU and host boards.

Prerequisites

The following installation information about the OMU board to be

replaced is obtained:

FTP server password

Administrator password

Operating system (OS) type of the OMU board

Information about all IP addresses of the OMU board, including

external fixed IP address (external gateway IP address), external virtual

IP address, internal fixed IP address, internal virtual IP address, backup

channel IP address of the active and standby OMUs, and debugging IP

address.

Page131


35pt

) :18pt

Checking OMU Status Before

Replacing an OMU Board

Check consistency in the configuration data, version

software, and license.

ACT CRC to check whether the configuration data of all

BSC6900 host boards and the OMU board is consistent.

CMP BRDVER to check whether the running versions of all

BSC6900 host boards and the OMU board are consistent.

CMP LICENSE to check whether the licenses of all BSC6900

host boards and the OMU board are consistent.
