Parameters

ID Name Meaning
1 Subrack No.

Subrack No.

2 Slot No.

Slot No.

3 Cpu No.

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 service quality of the standby CPU mapping to the faulty link decreases.

System Actions

  • For the active board in active/standby mode: The system performs switchover if the standby board is ready for the operation.
  • For the standby board in active/standby mode: No handling.

Possible Causes

  • The sub-board where the CPU mapping to the faulty link resides is not securely inserted.
  • The hardware of the peer board mapping to the faulty link fails.

Procedure

  1. Remove the GXPUx and tightly insert the sub-board where the CPU mapping to the faulty link CPU resides. Then, reinstall the GXPUx. After 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 is not cleared. Go to 2.

  2. Remove the GXPUx and replace the sub-board where the faulty link CPU resides. Then reinstall the GXPUx. After 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 is not cleared. Go to 3.

  3. Replace the GXPUx. After 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 is not cleared. Please contact Huawei Customer Service Center.
