OR
faulty port.
1. Wait 5 to 10 seconds. If the Power
Active LED turns ON, there was a
discharged capacitor in the IP
device.
2. Verify that you are not using any
crossover cables.
3. The IP device may require a local
power adapter to operate. If an
adapter is already in use, replace
it with a known working adapter. If
this works, replace the faulty
adapter.
4. Connect the IP device directly to
the Power Unit using a short
cable. If the device works
normally, the original cable (or one
of its connectors) is faulty.
5. Connect the IP device to a
different port pair. If the device
works, one of the original ports is
probably faulty, or there is a bad
RJ-45 connection.
6. Unplug the IP device, and verify
that the Power Inactive LED turns
OFF. If it does not, the port is
probably faulty, or the RJ-45
socket is shorted.
IP device powered
correctly, but
Power Active LED
is OFF.
Re-connect the IP device to a
different port pair. If the new port pair
Active Power LED turns ON, there is
a fault in the original output port
(probably a faulty LED).
IP device does not
work, but Green
Port Status LED
ON.
Wrong connection
OR
faulty IP device.
1. Verify that the IP device is actually
connected to that port.
2. Replace the device by a known
working IP device (test device). If
the test device powers up, the
original IP device is probably
faulty.
