Figure B-1. RJ-45 Connector Pin Numbers
Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for
RJ-45 connections: 100-ohm Category 3, 4 or 5 cable for 10 Mbps
connections or 100-ohm Category 5 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, 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.
