PD does not operate
1.
Verify that the port is enabled (Midspan did not
detect a PD).
2.
Verify that the PD is designed for PoE operation.
3.
Verify that you are using a standard Category
5/5e/6, straight-wired cable, with four pairs

4.
If an external power splitter is in use, replace it
with a viable splitter.
5.
Verify that the Data source is connected to the
Data In
port.
6.
Verify that the PD is connected to the
Data and
Power Output
port.
7.
Verify that there is no short over any of the
twisted-pair cables or over the RJ45 connectors.
End device operates, but there is no data link.
1.
If an external power splitter is in use, replace it
