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)

.
