Verify that an approved power cable is used.
Verify that the voltage at the power inlet is between
12-24V DC for Input voltage 1 and between 45-57V DC
for Input voltage 2.
Remove and re-apply power to the device and check
the indicators during power up sequence.
The Midspan did not detect a PD; and the port is not
enabled.
Verify that the PD is designed for PoE operation.
Verify that you are using a standard Category 5/5e/6,
straight-wired cable, with four pairs.
If there is an external PoE device connected, replace it
to verify that it is functioning properly.
Ensure that the input Ethernet cable is connected to
the Data In port.
Verify that the PD is connected to the Data & Power
port.
Try to reconnect the same PD into a different Midspan.
If it works, there is probably a faulty port or RJ-45
connection.
Verify that there is no shortcut over any of the twisted
pair cables or over the RJ45 connectors.
