Power Supply LED
Each power supply provides one green LED to indicate the status of the power supply. The LED
will be on when the power supply is on and receiving source power. If the source power exceeds
or drops below allowable tolerances, the LED turns off and an SNMP alarm is generated.
Power Supply Fan
Each power supply includes a built-in fan to ensure adequate cooling of the power supply. If the
fan should fail, replace the power supply immediately. Keep the fans clear of obstructions in
order to maintain adequate cooling.
