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 ”Heartbeat LED Blink

Patterns” on page 5-1 for more information about Heartbeat LED blink patterns.
