Activity N1: Testing LEDs
All front panel LEDs light for a few seconds, then all but the Ethernet
LED (segment indicator) turn off, confirming that all LEDs are
operational.
Activity N2: Testing the Hardware
During the power-up sequence, the CSMIM-T1 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 indicator flashes during the power-up
self-tests. After the self-tests complete, only the STAT and Ethernet
channel indicator remain on.
