Troubleshooting
This section provides a symptoms and resolutions to help you
troubleshoot minor operating problems. If the provided resolutions
do not solve your problem, call your local Intermec representative
for further assistance.
If you encounter problems
•
be sure that power is applied to the Power Bridge.
•
be sure that a “crossover” type Ethernet cable is not used.
•
be sure that the input Ethernet cable is connected to the Data In
port.
•
be sure that the output Ethernet cable is connected to the Power
& Data Out port.
Symptom Resolution
Power Bridge is
plugged in to the
main AC inlet but
does not power up. Verify that the AC power cord is correct and
functioning and that it has a solid ground connection.
Verify that the AC inlet is supplying power (test with a
different device) and that the voltage is between 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
operates, but the
Main LED is off. You may have an internal power supply fault.
The Power Active
LED is lit but the end
device does not
operate. The Power Bridge has successfully identified the end
device as Power over Ethernet Enabled and is providing
power. Try to connect a different end device to the
port—if the new device operates, you probably have an
internal fault in the previous end device.
The port is powering
an end device
without turning the
Active LED on. If possible, reconnect the end device to a different
bridge—if the LED lights, the previous bridge’s port is
faulty.
