1000BASE-T Pin Assignments

Caution: DO NOT plug a phone jack connector into any RJ-45 port.
The table below shows the 1000BASE-T MDI and MDI-X port pinouts.
These ports require that all four pairs of wires be connected. Note that for
1000BASE-T operation, all four pairs of wires are used for both transmit
and receive.
Use 100-ohm Category 5 or 5e unshielded twisted-pair (UTP) or shielded
twisted-pair (STP) cable for 1000BASE-T connections. Also be sure that
the length of any twisted-pair connection does not exceed 100 meters
(328 feet).
