Sub-product line: Access Network Line Product: MA5603T
[Problem Description]
In the 6 U MA5603T, when the H801BIUA board with the software of 117 or earlier versions works with
the SCUN, SCUL, and SCUF control boards, the H801BIUA board fails to register and is in the faulty
state all the time, and the board in slot 0 resets repeatedly.
[Cause Analysis]
The software version of the H801BIUA board is too early. In the 6 U MA5603T, the H801BIUA board
is installed in slot 12, and in other products which use the H801BIUA board with the software of 117
or earlier versions, the H801BIUA board can only be installed in slot 0. If the H801BIUA board with
the software of 117 or earlier versions is installed in slot 12 of the MA5603T, the master-slave
communications of the boards in slots 12 and 0 conflict with each other, the board in slot 0 resets
repeatedly and the H801BIUA board is in the faulty state all the time.
[Impact and Risk]
1. In the 6 U MA5603T(Huawei OLT), the H801BIUA board can not start up in the normal state.
2. In the 6 U MA5603T, the board in slot 0 resets repeatedly.
[Measures and Solutions]
Avoidance Measures:
Do not use the H801BIUA board with the software of 117 or earlier versions in the MA5603T.
Solution:
When the problem occurs, re-load the software of the H801BIUA board to the version that matches
the host version through the serial port cable (the BOM of the serial port cable is 04028285) of the
H801BIUA board. Upgrade the software of the H801BIUA board through the commissioning
subboard and then load the BIOS software online through the host.
[Supplementary Information]
The methods of checking the software version of the H801BIUA board are as follows:
(1) If the board is in use, run the display version command through CLI on the host.
For example:
MA5603T(config)#display version 0/12
Main Board: H801BIUA
—————————————
Pcb Version: H801BIUA VER B
Mab Version: 0001
Logic Version: (U21)102
Main CPU:
APP Version: 118(2009-1-17)
BIOS Version: 118
SubClockBoard:
PCB Version: H802CKMA VER B
Software Version: 103
Bios Version: 103
—————————————
The number after “APP Version” is the APP version of the board. The number after “BIOS Version” is the BIOS version of the board. (2) Use the related board commands to query the software version through the serial port on the board.

(3) Manually upgrade the BIOS and APP. 1) Install the H801BIUA board in the shelf and then connect the PC serial to the H801BIUA
board through the commissioning subboard H561SEDB. Log in to the H801BIUA board through
the serial port of the PC. For how to log in to the H801BIUA board through the serial port,
see the following figure:

to be loaded. Please Select Program File . XMODEM downloading …CCCC 4) The APP loading
is completed. 5) Upgrade the BIOS: install the board into the shelf and then run the following
command in the CLI of the host after the board is in the normal state.
MA5603T(config)#load program
{ emu<K>|ftp<K>|sftp<K>|tftp<K>|xmodem<K> }:xmodem

Command:
load program xmodem 0/12
Current baud rate is 9600bps, and it can be modified by ‘baudrate’ command
Are you sure to use this baud rate? (y/n)[n]:y
Whether to load other boards of same type ? (y/n)[n]:
Board name[H801BIUA]:
Whether to start loading? (y/n)[n]:y
You can also load the program in the tftp mode. 6) After the BIOS and the APP are loaded successfully, used methods (1) and
(2) in the preceding section to check whether the loaded versions are correct.
