Twisted-Pair Cable and Pin Assignments

For 10BASE-T and 100BASE-TX connections, the twisted-pair cable must

have two 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 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 “10BASE-T/100BASE-TX Pin Assignments”

on page B-2 for an explanation.)

The figure below 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.
