Figure 2-4.  Chassis LEDs
2.2.2.1
Input Power LED (Green)
The Input Power LED indicates the voltage status at the switch logic circuitry. This 
LED illuminates when the switch logic circuitry is receiving the proper DC 
voltages.
2.2.2.2
Heartbeat LED (Amber)
The Heartbeat LED indicates the status of the internal switch processor and the 
results of Power On Self Tests (POSTs). 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.
