Activity N1: Testing
LEDs 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.
Activity N2: Testing
the Hardware 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.
Normal Mode Error Sequence
Table 4-3 shows the state of the LEDs when an error occurs at various
stages of the start-up process. If the RAC fails during the hardware-test
state (N2), the error condition is hardware failure NE2. A description of
possible causes and solutions for each error condition follows.
