Description of the problem

A bureau OSN3500 device fails to expand a new standby SXCSA single board with a prompt of unsupported board type.

Alarm message

Device host: 5.21.30.15P02

Network management version: U2000V1R2

9-slot primary cross board for SXCSA veneer, BOM code: 03030KBM

Processing

1. Adding a single board on the network management fails, and the add operation through the command line still fails.

2、Suspecting that the board ID is incorrectly recognized, the physical board will be dialed out, and adding the logical single board still fails.

3, the scene to check the spare cross board BOM code is 03030KBM, and the main cross board consistent, to rule out the physical single board error.

4, check the host software supporting table, R9C03 host only supports PX cross boards, other cross boards are not supported.

5. Replace the main and backup cross boards of the network element with PSXCSA to solve the problem.

Root cause

1, single board software and host mismatch

2, board ID recognition error after the board is powered up

3, the host does not support the SXCSA single-board

Suggestions and Summary

NGSDH equipment single board and host software maintenance requirements for strong support.

The previous 9-slot SXCSA single board work reason, because the network element was originally MSTP version upgraded to MSTP + version, so the logic board has been in, due to the MSTP + version limitations do not support online add SXCSA single board.
