Detecting Faulty Hardware
When power is applied to the chassis, power is sequentially applied to the Management I/O (MIO/UMIO/MIO2)
cards, Data Processing Cards (DPC/UDPC/DPC2/UDPC2s), Fabric and Storage Cards (FSCs), and System
Status Cards (SSCs).
Each PFU and 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.
