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 and a message stating that the configuration is non-
redundant (
%CHMGR-1-MINOR_PS: Minor alarm: power supply non-redundant).
If only three power supplies are installed and one of them fails while the E300 System is operating, the
software generates a major alarm and an SNMP trap, lights the major LED, and activates the audible
alarm.
