Power Supplies Alarms
If a Power Supply fails while the E1200i is operating, the software generates a major alarm and an SNMP
trap, and lights the major LED.
When a Power Supply fails, the software also records one alarm event for line cards, RPM, and SFM3,
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.
AC Power Supplies and Alarms
During system boot, if the redundant power supply (the fourth power supply) is missing or fails, the
FTOS does not generate any alarm messages since the minimum configuration of three power supplies is
operating. Yet, if a fourth AC power supply is installed, and later one of the four power supplies is
removed or fails, the system generates a minor alarm.
