The PATCH_BD_MATCH_FAIL is an alarm indicating a board patch mismatch. An NE reports the PATCH_BD_MATCH_FAIL alarm if the patch software of a board fails to match with the patch package software on the system control board for three consecutive times after patch package loading completes.


Alarm Severity Alarm Type





Impact on the System

If the system control board reports a PATCH_BD_MATCH_FAIL, patch package loading may fail again. If another board reports a PATCH_BD_MATCH_FAIL alarm, the NE housing the board may report a PATCH_BD_MATCH_FAIL alarm again.

Possible Causes

The possible causes of the PATCH_BD_MATCH_FAIL alarm are as follows:

  • Cause 1: Board communication faults occur.
  • Cause 2: The board software is abnormal.


  1. Cause 1: Board communication faults occur.
    1. On the NMS, check whether communication fault alarms such as COMMUN_FAIL are reported. If any, clear the alarms.
    2. Then, check whether the PATCH_BD_MATCH_FAIL alarm is cleared. If the alarm persists, go to 2.
  2. Cause 2: The board software is abnormal.
    1. On the NMS, manually isolate the board and rectify the board software fault.
    2. Restart matching between the board patch software and the patch package software on the system control board.
    3. Check whether the alarm is cleared. If the alarm persists, contact Huawei engineers to handle the alarm.
