8.1 PoE Injector
Problem Solution
The Device Does Not
Work
`
Make sure that you are using a standard UTP
– Category 5e/6 cable in case of MP-8100-BSU, MP-8100-SUA, MP-8150-SUR,
MP-8150-SUR-100, MP-8160-BSU, MP-8160-BS9, MP-8160-SUA,
QB-8100-EPA/LNK, QB-8150-EPR/LNK, QB-8150-LNK-100, QB-8151-EPR/LNK,
MP-8200-BSU, MP-8250-BS9, MP-8250-BS1, MP-8200-SUA,
MP-820-BSU-100, MP-820-SUA-50

, and QB-8200-LNK devices
– Category 5/5e cable in case of MP-8150-CPE, MP-8160-CPE-A100,
MP-825-CPE-50, QB-825-EPR/LNK-50, and QB-8150-LNK-12/50
`
Try a different port on the same PoE Injector hub (remember to move the input port
accordingly) – if it works then there is a problem in the previous RJ45 port or a bad
RJ45 port connection.
`
Try to connect the device to a different PoE Injector hub.
`
Try using a different Ethernet cable – if it works, there is probably a fault in the cable
or its connection.
`
Check the power plug and hub.
`
If the Ethernet link goes down, check the cable, cable type, switch and hub.
There is No Data Link
`
Verify that the indicator on the device port is “ON.”
`
Verify that the Ethernet cable from PoE Injector hub to the Ethernet port of the
device is properly connected.

`
The length of the cable from the Ethernet port of the device to the PoE should be
less than 100 meters (approximately 325 feet).
`
Try to connect a different device to the same port on the PoE Injector hub – if it
works and a link is established then there is probably a fault in the data link of the
device.
`
Try to re-connect the cable to a different output port (remember to move the input
port accordingly) – if it works then there is a fault probably in the output or input
port of the PoE Injector hub or a bad RJ45 connection.
Overload Indications
`
Connect the device to a PoE Injector.
`
Ensure that there is no short over on any of the connected cables.
`
Move the device into a different output port (remember to move the input port
accordingly) - if it works then there is a fault probably in the previous RJ45 port or
bad RJ45 port connection.
