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 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 as shown on the following pages.
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.
