Step 5

Replace the AISU.

After replacing the AISU, remove the abnormal AISU, and scan, add, and configure the new
AISU. After 5 minutes, check whether the alarm is cleared.



If the alarm is cleared, no further action is required.



If the alarm persists, contact Huawei technical support engineers.

After replacing the AISU, reconfigure the AISU by referring to section 5 "
