3. Verify 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 PD is connected to Data & Power Output port.
6. Try to reconnect the same PD to a different port on the same Midspan or on
another midspan. If it works, there is probably a faulty output port or RJ45
connection.
7. Verify port shutdown command was not issued through web management.
8. If PD is an old PD, set the Port to Legacy mode through the port
management.
End device operates, but there
is no data link.
1. Verify port indicator on front panel is continuously lit.
2. If an external power splitter is in use, replace it with a viable splitter.
3. Verify that for this link you are using a standard UTP/FTP Category 5
straight (non-crossover) cabling, with all four pairs, and that link is 100
meters long or less.
