Insert and crimp the shielded RJ-45 connector. Use a crimp tool for RJ-45 connectors to prepare the
wires. Insert them into the appropriate pins and use the tool to crimp the connector. All 8 pins must
be connected (see details in Table B-1 below). Make sure to do the following:
»
Remove as small a length as possible of the external jacket. Verify that the external jacket is well
inside the sealing gland when connected to the unit, to ensure good sealing.
»
Pull back the shield drain wire before inserting the cable into the RJ-45 connector, to provide a
good connection with the connector's shield after crimping. To ensure a good shielding
connection solder the shield wire to the connector’s shield after crimping.
6
Connect the cable to the Ethernet connector.
7
Firmly push the rubber bushing back into place inside the base of the gland.
8
Close the nut using the extraction key supplied with the unit or an equivalent tool and tighten it
firmly to ensure proper sealing.
The PoE Injector provides power over 1Gbps Ethernet, meaning that there are no spare wires. All wires
are used for power and data concurrently:
