Twisted-Pair Cable Assignments
Caution: DO NOT plug a phone jack connector into the RJ-45 port.
Use only twisted-pair cables with RJ-45 connectors that
conform with FCC standards.
For 10/100BASE-TX connections, a 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: Each wire pair must be attached to the RJ-45 connectors in a
specific orientation. (See “Straight-Through Wiring” on page
B-3 and “Crossover Wiring” on page B-3 for an explanation.)
The following figure 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.
