Twisted-Pair Cable and Pin Assignments
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
connector in a specific orientation.
