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).
