Power Supplies and Alarms
If a Power Supply fails while the E1200i is operating, the software generates a major alarm and an SNMP
trap, lights the major LED, and activates the audible alarm.
When a Power Supply fails, the software also records one alarm event for line cards, RPM, and SFM,
though each contains its own power source. The system generates one alarm event and SNMP trap
summarizing the Power Supply failure and the components affected.
