Problem/Question Possible Solution/Answer
The Power Bridge is
plugged into the main
AC inlet but does not
power up. Verify that the AC power cord is correct,
functioning, and has a solid ground connection.
Verify that the AC inlet is supplying power (test
with a different device) and that the voltage is
from 100 to 264 VAC (50 to 60 Hz).
Reconnect the Power Bridge to the AC inlet and
verify the LED power up sequence.
Power Bridge is plugged
in and running, but the
fans are not working. Verify that none of the fan openings in the case
are blocked.
If fans are not working, you may have an internal
power supply fault.
Power Bridge operates
but the AC/Main LED is
off. If both internal fans are working (i.e., air flows
out of the case or can be heard), you may have an
internal circuitry fault.
If fans are not working, you may have an internal
power supply fault.
The Power Bridge has
powered up and the
Alarm LED remains lit,
or the Main LED is lit
(or blinks) in red. See the LEDs section in this guide, and
determine if the Power On Self Test (POST)
sequence works as listed. If the LEDs light up in
the correct sequence, the Power Bridge is fully
operational.
If the Alarm LED remains lit following the
POST sequence, the Power Bridge POST
detected an internal fault. Contact your local
dealer.
The Power Active LED is
lit, but one of the end
devices does not operate. Verify that the Power Active LED that is lit
corresponds to the end device that is not
working.
The Power Bridge successfully identified the end
device as Power over LAN Enabled and is
providing power. Connect a different end device
to the same port—if the end device operates, the
previous end device is faulty.
