SSIGNMENTS
For 10/100BASE-TX connections, a 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.
N
OTE
:
Each wire pair must be attached to the RJ-45 connectors in a specific
orientation.
C
AUTION
:
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.
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.
