Twisted-Pair Cable and Pin Assignments
Caution: DO NOT plug a normal phone jack connector into any RJ-45
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: Each wire pair must be attached to the RJ-45 connectors in a

sure to hold the connectors in the same orientation when attaching the wires
to the pins.

conform with FCC standards.
