A Troubleshooting the NJ220
If you encounter problems with the IntelliJack:
■ Verify the IntelliJack is receiving power by viewing the Power LED (it should be on). If
the Power LED is not on, make sure that:
■ If using power over Ethernet, the other end of the network cable is plugged
into a switch on the network that has Power Over Ethernet integrated into it,
or one that feeds into an external midspan power supply that supports Power
Over Ethernet.
■ The local power supply is plugged into the IntelliJack and into a working
electrical outlet, if your network does not support Power Over Ethernet.
■ Verify the IntelliJack is connected to the network properly by viewing the Link LED (it
should be on). If the Link LED is not on, make sure the network cable:
■ Is terminated properly. Refer to the connector manufacturer’s instructions for
terminating the cable. Be sure to test the connector and verify it is working.
■ Has a valid connection to the network.
■ Adheres to proper length and cabling specifications for your network.
■ The IntelliJack is configured for manual MDI. Be sure to use a straight-through cable.
If you want to use a cross-connect cable, you must change settings in the
Configuration Manager software.
