WISTED AIR
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.
CAUTION: DO NOT plug a phone jack connector into a power injector 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.
