Hi there!
This time, I will share with you a case about how to precaution the using problem of Huawei MA5603T product.
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 reset 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:
