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 100BASE-TX/10BASE-T 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. (See “Cabling Guidelines” on page 4-1 for

an explanation.)

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.
