A port indicator is
not lit and the PSE
(Power Supply

1. The extender does not detect a PSE; and
the port is not enabled.
2. Verify that the IP Device is designed for
PoE operation (i.e. PoE Enabled).
3. Verify that you are using a standard
Category 5/5e/6, straight-wired cable,
with four pairs.
4. If there is an external PoE device
connected, replace it to verify that it is
functioning properly.
5. Ensure that the input Ethernet cable is
connected to the
“Data or PoE IN” RJ-45
port.
6. Verify that the PSE is connected to the
“Data or PoE IN” port.
7. Try to reconnect the same PSE into a
different extender. If it works, there is
probably a faulty port or RJ-45
connection.
8. Verify that there is no shortcut over any
of the twisted pair cables or over the
RJ45 connectors.
The end device
operates, but there
is no data link
1. Verify that the port indicator on the rear
panel is continuously lit.
2. If an external network device is in use,
replace it with a good one.
3. Verify that for this link, you are using
standard UTP/FTP Category 5 straight
(non-crossover) cabling, with all four
