RJ-45 Port and Cable Assignments
CAUTION: DO NOT plug a phone jack connector into any RJ-45
port. Use only twisted-pair cables with RJ-45
connectors that conform with FCC standar ds.
The RJ-45 port on the SMC6900GT module supports 1000, 100,
and 10 Mbps Ethernet operation, with auto-negotiation of speed,
duplex mode, and flow control.

1000BASE-T Pin Assignments

1000BASE-T ports switch 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. In
straight-through cable, pins 1-8, at one end of the cab le, are
connected straight through to pins 1-8 at the other end of the
cable.
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)
