In an OSN project, the OptiX OSN 3500 and OptiX OSN 1500 form an SNCP ring. Three optical ports on the N1SLQ1 of the OptiX OSN 3500 are not used. Hence, the R_LOS alarm is suppressed for the three optical ports. Then, the IN_PWR_ABN alarm, however, is reported.
Suppress the IN_PWR_ABN alarm.
After a higher level alarm is suppressed, the lower level alarms that are suppressed by this higher level alarm are reported. For example, after the R_LOS alarm is suppressed, the IN_PWR_ABN alarm is reported.
When you suppress an alarm, note that the lower level alarms that are suppressed by this alarm will be reported.
Figure 1 shows the inter-board suppression relations among common alarms.
