When the switch is powered on, it performs its diagnostic self test. The entire
download, initialization, and self test process can take up to 2 minutes for a
fully loaded chassis, depending on the number and type of modules installed
in the switch.

LED Behavior:

During the self test:
Initially, Power and Fault, and all the switch chassis LEDs are on. Then,
■
after approximately 30 seconds, all the module LEDs go on as the modules
receive power and code is downloaded to them, the Fault LED goes off,
and the chassis LEDs go off except Power, Self Test, Fan Status, and Power
Status.
■ When the download of code to the modules is completed, the module
LEDs go off. You may see each port LED go on briefly, in sequence, as the
port is tested.
For the duration of the self test, the Self Test LED stays on.
■
When the self test completes successfully:
The Power LED stays on, and the Status LEDs on the switch chassis stay
■
on for the devices installed: one for each switch module installed, one for
each power supply installed, and one for all the fans.
The Fault and Self Test LEDs are off.
■
■ The port LEDs on the switch modules go into their normal operational
mode:

If the ports are connected to active network devices, the Link LEDs
stay on and the Mode LEDs behave according to the mode selected.
In the default mode (Activity), the Mode LEDs should flicker showing
network activity on the port.
If the ports are not connected to active network devices, the LEDs
will stay off.
