Attribute

Alarm ID	Alarm Severity	Alarm Type
21019	Critical	Fault

Parameters

ID	Name	Meaning
1	Subrack No.	Number of the subrack where the board on which the loading fails is located
2	Slot No.	Number of the slot where the board on which the loading fails is located
3	CPU No.	Number of the CPU on which the loading fails (GXPUx has four CPUs numbered from 0 to 3; other boards have only one CPU numbered 0)
4	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 corresponding board or CPU is not available. The board cannot work normally.

System Actions

The board is reset automatically. Make an attempt to load software from the GBAM/GOMU. If the loading fails again, the board will be reset repeatedly with an internal of about 10-30 seconds.

Possible Causes

The GSCU in the GMPS or where the GBAM/GOMU is located is faulty.
The communication among the GBAM/GOMU, the GSCU, and the faulty board is abnormal.
The files under the directory of the version area on the GBAM/GOMU are damaged.
The board hardware (such as flash device) is faulty.

Procedure

Wait one minute, and then check whether the alarm is cleared.
