What will happen if you falsely match Software Package with OSN 8800 Platform Subrack

Summary: When an Huawei OptiX OSN 8800 platform subrack is falsely connected to the master subrack of V100R006C01SPC100, SPC200, SPC300, or SPC500 version as a slave subrack, the master subrack will automatically match the software package for the slave subrack. As a result, the TN15AUX board in the OptiX OSN 8800 platform subrack resets repeatedly and cannot be managed.

Problem Description
Triggering conditions:
The OptiX OSN 8800 platform subrack is connected to a master subrack of the V100R006C01SPC100, SPC200, SPC300, or SPC500 version as the slave subrack.
Symptom:
If the Optical transmission equipment OSN 8800 subrack is falsely connected to a master subrack of the V100R006C01SPC100, V100R006C01SPC200, V100R006C01SPC300, or V100R006C01SPC500 version as the slave subrack, the master subrack will automatically match the software package for the slave subrack. That is, the TN15AUX board software of the R6 version is matched for the TN15AUX board in the OptiX OSN 8800 platform subrack of the R7 version. The TN15AUX board resets repeatedly and the subrack cannot be managed because the TN15AUX board software of R6 version has defects.
Under this circumstance, this problem persists even if the faulty OptiX OSN 8800 platform subrack is connected to a normally operating master subrack of the R7 version again. Therefore, replacing the faulty TN15AUX board is the only method to solve the problem.
Identification method:
1. The version of the master subrack is V100R006C01SPC100, V100R006C01SPC200, V100R006C01SPC300, or V100R006C01SPC500.
2. The slave subrack is the OptiX OSN 8800 platform subrack.
Root Cause
The TN16AUX board software in the software package of the V100R006C01SPC100, V100R006C01SPC200, V100R006C01SPC300, or V100R006C01SPC500 version applies to both the TN15AUX and TN16AUX boards.
If the TN16AUX board software of the V100R006C01SPC100, V100R006C01SPC200, V100R006C01SPC300, or V100R006C01SPC500 version is installed for a TN15AUX board, the board will reset repeatedly.

Impact and Risk
The TN15AUX board resets repeatedly, and the OptiX OSN 8800 platform subrack cannot be managed.

Measures and Solutions
Recovery measures
Give up the  faulty TN15AUX board and go to a  Huawei transmission equipment vendor to buy a new one.
Preventive measure:
Prevent the OptiX OSN 8800 subrack from connecting to the master subrack of V100R006C01SPC100, V100R006C01SPC200, V100R006C01SPC300, or V100R006C01SPC500 version as a slave subrack.
Solutions:
No solution is available.
