The chassis LEDs shown in 

 provide status information about switch 

operation. Refer to 

 for information about port LEDs.

The Over Temperature LED provides status information about the air temperature 
inside the switch. This LED illuminates to indicate that the switch logic circuitry is 
overheating. Refer to 

 for information about 

troubleshooting over temperature conditions.

The Fan Fail LED indicates operational status of the fan. This LED illuminates if 
the speed of the fan falls below the normal range. If the Fan Fail LED illuminates, 
isolate the switch from the fabric, unplug the switch from the AC power source, 
and contact your authorized maintenance provider.

The Heartbeat LED indicates the status of the internal switch processor and the 
results of the Power On Self Test (POST). Following a normal power-up, the 
Heartbeat LED blinks about once per second to indicate that the switch passed 
the POST and that the internal switch processor is running. In maintenance mode, 
the Heartbeat LED illuminates continuously. Refer to 

 for more information about Heartbeat LED blink patterns.
