6 Alarm Attribute

0=Normal, Alarms period are longer than the Transient Threshold.

1=Transient Count, The times and the period of the alarms whose periods are shorter than the Transient Threshold are summed up. If the sum result is longer than the Alarm Occurrence Period Threshold or Alarm Occurrence Times Threshold, an alarm so called Transient Count Alarm is triggered. Because Transient Count Alarm is based on accumulative result, the recovery of the alarm may occur at least one Summing Cycle later. The Summing Cycle can be query by MML "LST STATSLDWIN".

Impact on the System

The services may be interrupted.

System Actions

Reset the board.

Possible Causes

  • The chip clock is not working steadily.
  • The chip is faulty.

Procedure

  1. After the board is automatically reset, wait until the new board is successfully restarted. Check whether the alarm is cleared.

    Y => The alarm is cleared. The alarm handling is complete.

    N => The alarm persists. Go to 2.

  2. Replace the board that reports the alarm and check whether the alarm is cleared.

    Y => The alarm is cleared. The alarm handling is complete.

    N => The alarm persists. Please contact Huawei Customer Service Center.
