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 the Software Installation and Coldloading Manual (Part No. T0028) for more information.
