1000BASE-T Pin Assignments
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).
