When POST completes successfully, the port LEDs return to the status mode
display, showing that the switch is operational. If a test fails, the port LED
associated with the test turns amber, and the system LED turns amber.
Note POST failures are usually fatal. Call Cisco Systems if your switch does not pass
POST.
