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 connectors
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.
