If only three power supplies are installed and one of them fails while the E1200 is operating, the software
generates a major alarm and an SNMP trap, lights the major LED, and activates the audible alarm.
When you operate the E1200 with three AC power supplies and six or more line cards, the software lists
a redundancy alarm on the console and in the
show alarms
command output. All line cards operate
normally.
SFM3s and Alarms
The number of SFM3s present in the system when it boots determines the level of alarms sent when a
redundant SFM3 is removed or fails. At boot time, if 9 or 10 SFM3s are present and functioning, the
E1200 system issues no alarms. However, if one SFM3 fails or is removed, the system sends a minor
alarm. The system requires eight functioning SFM3s to pass traffic.
At boot time, if eight SFM3s are present and functioning, the E1200 system issues no alarms. The system
issues no alarms if an SFM3 is added to the system; however, if the number of functioning SFM3s
changes from nine to eight, the system sends a minor alarm event. The system always triggers a major
alarm when the number of working SFM3s reaches seven.
