Appendix B. Pin Assignments
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).
