The PD does not operate:
•
Verify that the PoE Injector detects a PD.
•
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 an external power splitter is in use,
replace it with a known-good splitter.
•
Ensure 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 PoE Injector.
If it works, there is probably a faulty port or RJ45 connection.
•
Verify that there is no short over any of the twisted pair cables or
over the RJ45 connectors.
The end device operates, but there is no data link:
•
Verify that the port indicator on the front panel is continuously lit.
•
If an external power splitter is in use,
replace it with a known-good splitter.
•
Verify that for this link, you are using standard UTP/FTP Category 5
straight (non-crossover) cabling, with all four pairs.
•
Verify that the Ethernet cable length is less than 100 meters from the
Ethernet source to the load/remote terminal.
•
Try to reconnect the same PD into a different PoE Injector If it works,
there is probably a faulty port or RJ45 connection
