Detecting Faulty Hardware

When power is applied to the chassis, power is sequentially applied to management cards, application cards and line
cards.

Each PFU, application and line card installed in the system incorporates light emitting diodes (LEDs) that indicate its
operating status. This section describes how to use these status LEDs to verify that all of the installed components are
functioning properly.

Important:

As the system progresses through its boot process, some cards will not exhibit immediate LED

activity. Allow several minutes to elapse after a reboot is initiates before checking the LEDs on the various cards to
verify that the boot process has successfully completed.

Using the CLI to View Status LEDs

The status of application and line card LEDs can be viewed through the CLI by entering the show leds all command in
Exec mode.

[local]host_name# show leds all

The following displays a sample of this command’s output.

The status of the two Power Filter Units (PFUs) can be viewed by entering the show power chassis command in the
Exec mode.
