1000BASE-T Pin Assignments

All 1000BASE-T ports support automatic MDI/MDI-X operation, so you
can use straight-through cables for all network connections to PCs or servers,
or to other switches or hubs.
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, 5e or 6 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).
