1000BASE-T Pin Assignments

1000BAST-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. (Auto-negotiation must be enabled to
support MDI/MDI-X.)
The table below shows the 1000BASE-T MDI and MDI-X port pin outs. 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).
