SSIGNMENTS
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.
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.

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.
