Ethernet Cable

Caution:

Do not plug a phone jack connector into an RJ-45 port.

For

Ethernet connections, use only twisted-pair cables with RJ-45

connectors that conform to FCC standards.

Specifications

Wiring Conventions

For Ethernet 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 red and the other, red with white stripes. Also, an RJ-45 connector

must be attached to both ends of the cable.

Each wire pair must be attached to the RJ-45 connectors in a specific

orientation. The following figure illustrates how the pins on an Ethernet RJ-45

connector are numbered. Be sure to hold the connectors in the same

orientation when attaching the wires to the pins.
