B CABLES
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 m ust have four pairs
of wires. Each wire pair is identified by two different colors. For ex ample, 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.
C
AUTION
:
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.
C
AUTION
:
Each wire pair must be attached to the RJ-45 connectors in
a specific orientation.
The figure below illustrate s how the pins on the RJ-45 con nector are numbered.
Be sure to hold the connectors in the sa me orie n tation when attaching the wires
to the pins.
