20191 Board Faulty-Link Disconnection on the Service Port

Description

The link of traffic network port is disconnected.

Alarm ID	Alarm Severity	Alarm Type
20191	Major	Fault

ID	Name	Meaning
1	Subrack No.	Subrack No.
2	Slot No.	Slot No.
3	Cpu No.	CPU No.
4	Ethernet Port No.	0=Service Ethernet Port,1=Q922 Ethernet Port,3=Panel Ethernet Port,4=UOIP Ethernet Port,5=HOM Ethernet Port
5	PHY Fault Type	0=Link Normal,1=Link Down,2=Link Tx Faulty,4=Link Rx Faulty,6=Link Tx and Rx Faulty
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".

The services associated with the fault CPU stop.

As the handling procedures vary for different types of boards, please specify the type of the board in advance by the subrack number and slot number where the board is located. If the GXPUx is faulty:
1. Remove the board and secure the sub-board (No.0 and No.1 CPUs are on upper side of the board, No.2 and No.3 CPUs are on the lower side of the board) where the faulty CPU is located. Check whether the alarm is cleared.
  Y => The alarm is cleared. The alarm handling is complete.
  
  N => The alarm persists. Go to b.
2. Replace the board and 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. Please contact Huawei Customer Service Center.
