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.

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.

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.

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.

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.

value of OS type.
Run the MML command LST MBSCMODE. Query and
record the OMU mode.
Query and record the external gateway IP address of the
OMU board to be replaced.

If two OMU boards are configured, Check whether the
OMU board to be replaced is active or on standby.
The board is in Standby normal state, Replacing the Standby
OMU in Dual-System Mode.
The board is in Active normal state, SWP OMU to manually
switch over the active and standby OMU boards.
