Corrective Steps
1. Verify a reliable power cord is used.
2. Verify voltage at the power inlet is between 100-
240VAC.
3. Remove and re-apply power to the device.
1. Verify that the unit detects a PD.
2. Verify that the PD is designed for PoE operation.
3. Verify that a standard Category 5/5e/6 cable is in
use - Straight wired cable, with four pairs.
4. If an external power splitter is in use, replace it with
a splitter known as good.
5. Ensure input Ethernet cable is connected to the
Up-link port.
6. Verify that the PD is connected to the
Data & Power port.
7. Try reconnecting the same PD to a different PoE
switch. If it works, there's a probable faulty port or
a faulty RJ45 connection.
8. Verify there is no short over any of the twisted pair
cables or over the RJ45 connectors.
1. Verify the port indicator on unit GUI (Wed page) is
Continuously lit.
2. If an external power splitter is in use, replace it with
a splitter known as good.
3. Verify that for this link, you are using standard
UTP/FTP Category 5 straight (non-crossover)
cabling, with all four pairs.
4. Verify Ethernet cable length is less than 100
meters from Ethernet source to the remote
terminal.
5. Try to reconnect the same PD to a different PoE
switch. If it works, there's a probable faulty port or
a faulty RJ45 connection.
