This section contains FRUs that have LED indicators. Each listed assembly is shown with a
description of its LEDs. While CEC enclosure LED
indicators might indicate a failure, do not use them as a starting point for a repair.

Notes:
During CEC power-on, there is approximately a 30-second transition period between flashing to
solid when the LED might flash faster.
