4.9.3 Failure Indications
As the self-test progresses, the LEDs display the current state. At the end of the test,
a power-up with no errors is indicated by all LEDs turned off and by immediate entry
into the boot scanner.
If a failure occurred during the self-tests, then that failure is indicated on the LEDs at
the end of the tests. If there was more than one failure, the highest priority failure is
indicated on the LEDs.
