Media	IEEE Standard		Connector
Twisted Pair (CAT 5)	10BASE-T		RJ-45
Twisted Pair (CAT 5)	100BASE-TX		RJ-45

NOTE : It is recommended that high quality CAT. 5 cables (which work for both 10 Mbps and 100Mbps) be used whenever possible in order to provide flexibility in a mixed-speed network, since P80-series switch ports are auto-sensing for either 10 and 100Mbps. Note that the auto-cross function does not operate, if the port is fixed or not supporting auto-negotiation.

3.8.1Connecting Twisted Pair (RJ-45, CAT 3 or CAT 5, Unshielded or Shielded)

The following procedure describes how to connect a 10BASE-T or 100BASE-TX

twisted pair segment to the RJ-45 port. The procedure is the same for both unshielded and shielded twisted pair cables.
