Twisted-Pair Cable and Pin Assignments
Caution: DO-NOT plug a phone jack connector into any RJ-45
port. Use only twisted-pair cables with RJ-45 connec-
tors that conform with FCC standards.
For 10BASE-T/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 red and the
other, red with white stripes. Also, an RJ-45 connector must be
attached to both ends of the cable.
Caution: Each wire pair must be attached to the RJ-45 connectors
in a specific orientation.
Figure B-1 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.
