For standard category 5e or better, non-propreity Ethernet cables follow the
guldelines below.
2.8.0.1 Preparing Ethernet Cables
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. 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 cover 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 ensure a good connection with the connector's shield after
crimping.
 For 10/100BASE-TX connections, a twisted-pair cable must have two pairs of
wires. Each wire pair is identified by two different colors. For example, one
wire might be green and the other, green with white stripes. Also, an RJ-45
connector must be attached to both ends of the cable.
The following figure illustrates how the pins on the RJ-45 connector are
numbered. Be sure to hold the connectors in the same orientation when attaching
the wires to the pins.
CAUTION
Each wire pair must be attached to the RJ-45 connectors in a specific orientation.
DO NOT plug a phone jack connector into the RJ-45 port. Use only twisted-pair cables with RJ-45
connectors that conform with FCC standards.
