Twisted-Pair Cable and Pin Assignments

For 10/100BASE-TX connections, the twisted-pair cable must have two

pairs of wires. For 1000BASE-T connections the twisted-pair cable must

have four 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.

Caution: DO NOT plug a normal phone jack connector into any RJ-45

port. Use only twisted-pair cables with RJ-45 connectors that

conform with FCC standards.

Caution: Each wire pair must be attached to the RJ-45 connectors in a

specific orientation. (See “Cabling Guidelines” on page 4-3 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.
