AC Power Supplies and Alarms
During system boot, if a redundant power supply is removed or fails, Dell Networking OS generates a
minor alarm message.
If only two power supplies are installed and one of them fails, Dell Networking OS generates an alarm
and an SNMP trap (if configured), and lights the RPM alarm LED and power supply LED.
