10BASE-T/100BASE-TX Pin Assignments
Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for
RJ-45 connections: 100-ohm Category 3 or better cable for 10 Mbps
connections, or 100-ohm Category 5 or better cable for 100 Mbps
connections. Also be sure that the length of any twisted-pair connection does
not exceed 100 meters (328 feet).
The RJ-45 ports on the switch base unit 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, 2, 3, and 6, at one end of the cable, are connected straight through to
pins 1, 2, 3, and 6 at the other end of the cable. When using any RJ-45 port
on this switch, you can use either straight-through or crossover cable.
