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 1000BASE-T connections, a twisted-pair cable must have four 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 4-2 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.
