Relation of the Alarm Indicators on the EFI Boards in the Subracks of the OptiX OSN 6800

Publication Date:  2012-07-25 Views:  41 Downloads:  0
Issue Description
What is the relation of the alarm indicators on the EFI boards in the master and slave subracks when the OptiX OSN 6800 adopts the master/slave mode? 
Alarm Information
Null
Handling Process
1. The current master and slave subracks of the OptiX OSN 6800 report the alarms. Suppress all alarms reported by the master subrack. Then, check the EFI alarm indicators of the master and slave subracks. The check result shows that the states are consistent.
2. Suppress all alarms of the master and slave subracks simultaneously. The alarm indicators of all the master and slave subracks are off. Enable the alarms of the master subrack, and then check whether the states of the EFI alarm indicators of all master and slave subracks are consistent. 
 
Root Cause
In master/slave mode, the EFI alarm of each subrack is the same, which indicates the alarm status of the entire NE rather than the alarm of each subrack. 
Suggestions
1. In master/salve mode, if the master or slave subrack reports an alarm, the alarm indicators on the EFI boards in all subracks on the entire NE are consistent, which indicate the alarm status of the entire NE.
2. It is recommended to solve the problem completely in later versions. That is, the EFI state of the master subrack indicates the alarm status of the entire NE, whereas the slave subrack displays the alarm status of only the slave subrack.
