Troubleshooting
8.1 PoE Injector
Problem Solution
The Device Does Not • Make sure that you are using a standard UTP
Work
- Category 5e/6 cable in case of MP-8100-BSU, MP-8100-SUA, MP-8150-SUR,
MP-8160-BSU, MP-8160-SUA, QB-8100-EPA and QB-8150-EPR devices
- Category 5 cable in case of MP-8150-CPE, MP-8160-CPE,
QB-8150-EPR-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.
• 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-8160-BSU, MP-8160-SUA, QB-8100-EPA and QB-8150-EPR devices
- Category 5 cable in case of MP-8150-CPE, MP-8160-CPE,
QB-8150-EPR-12/50 devices
• 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.
8.2 Connectivity Issues
Connectivity issues include any problem that prevents from powering or connecting to the device.
