This chapter describes how to interpret the status of the LEDs on the pedestal
and use them as a troubleshooting aid during a pedestal malfunction. Both the
pedestal LEDs and the LEDs on the major components are covered. The
chapter also describes how to replace a Field Replaceable Unit (FRU) and how
to reconfigure the SCSI bus.
