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.

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.
