When POST completes successfully, the System LED remains green. The RPS
LED remains green for some time and then returns to its operating status. The
other LEDs turn off and return to their operating status.
Note For information on operating status for the LEDs, go to the “LEDs” section on
page 1-15.
Note POST failures are usually fatal. Call Cisco Systems if your switch does not pass
POST.
