What Is The Relationship Among The Alarm Indicators On The EFI Boards? by jorna: 4:31am On Jun 27, 2016 |
This section describes the relationship among the alarm indicators on the EFI boards in OptiX OSN 6800 subracks. Product OptiX OSN 6800 Fault Type Other Symptom What is the relationship among the alarm indicators on the EFI boards in OptiX OSN 6800 subracks if the OptiX OSN 6800 NE adopts the master-slave subrack mode? Cause Analysis If the OptiX OSN 6800 NE adopts the master-slave subrack mode, the alarm indicators on the EFI boards in all the subracks are in the same state. That is, these alarm indicators indicate the alarm status of the entire NE rather than the alarm status of the individual subracks. Procedure Suppress all the alarms reported by the boards in the master subrack of an OptiX OSN 6800 NE (assume that the boards in both the master and slave subracks report alarms). Then, check whether the alarm indicators on the EFI boards in the master and slave subracks are in the same state. Suppress all the alarms reported by the boards in the master and slave subracks. The alarm indicators on the EFI boards in all the subracks are off. Then, unsuppress the alarms reported by the boards in the master subrack. Check whether the alarm indicators on the EFI boards in all the subracks are in the same state. Result If the OptiX OSN 6800 NE adopts the master-slave subrack mode, the alarm indicators on the EFI boards in all the subracks are in the same state in case of an alarm reported by a board in either the master subrack or a slave subrack. That is, these alarm indicators indicate the alarm status of the entire NE. Reference Information None. |
