RJ-45 station ports can be attached to any device which use a
standard network interface (e.g., a workstation, server, bridge or
router). RJ-45 daisy-chain ports can be cascaded to a station
port on similar networking devices (e.g., another switch or hub).
Use unshielded twisted-pair (UTP) for RJ-45 connections: 100
ohm Category 3,4 or 5 cable for 10Mbps connections or 100
ohm Category 5 cable for 100Mbps connections. Also be sure
that the length of any twisted-pair connection does not exceed
100 meters (328 feet).
