All front-panel LEDs (and the Link LED on the rear panel) light for a
few seconds, then all turn off, confirming that all LEDs are operational.
During the power-up sequence, the RAC runs a series of self-test
diagnostics. These diagnostics test internal hardware functions. If a test
fails, the ATTN and STAT LEDs flash and an error message is displayed
on the console port. The TRAF LED flashes during the power-up self-
tests. After the self-tests complete, only the STAT and TRAF LEDs
remain on.
