When the PathBuilder S21x switch power cord is plugged into the power supply
outlet, you will see the following powerup sequence:
Hardware Failure
If the TEST light turns on and remains on, one or more of the diagnostic tests have
failed, indicating there is a hardware problem. Contact 3Com for possible repairs to
your PathBuilder S21x switch.
Diagnostic Failure
If the TEST light does not blink at all, but the Status light is on, the diagnostic
software image is corrupted. Perform a download of the software option bundle.
Powerup Failure
If the STATUS light blinks continuously, at a constant rate, the software bundle in
Flash memory is corrupted. Perform a cold load of the software option bundle. See
