Bridge Status LEDs

See chapter 5, "Troubleshooting", for information using these LEDs to diagnose errors.
Pwr – power (green) is ON if the bridge
is receiving power and if power is being
supplied to internal and external transceivers.
Self-test (green) is ON when a self-test is
executing on the bridge. This occurs when
the bridge has just been powered on,or a
bridge reset is in progress. If an error is
found during self-test, this LED stays ON
and the Fault (and possibly Net Fail) LED
will go ON.
Fault (yellow) is ON if the bridge or network has failed during reset or normal operation.
(This LED is repeated on the front.) If this LED is ON and one of the Net Fail LEDs is also
ON, the failure is associated with the network. If this LED is ON and a Net Fail LED is not
ON, the bridge itself is at fault.
