3.8 Connecting Twisted Pair (RJ-45 ports)
The PXES4P Series Switches can be connected to only one media type with two
different speed i.e. 100BASE-TX and 10BASE-T. CAT 5 cables should be used when
making 100BASE-TX connections. When the ports are used as 10BASE-T ports, CAT 3
may be used. In either case, the maximum distance for unshielded twisted pair cabling is
100 meters (328 ft).
Media
IEEE Standard Connector
Twisted Pair (CAT 3 or 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 PXES4P Series switch ports are auto-cross(MDIX)
for either 10 and 100Mbps. Note that the auto-cross function does not operate, if
the port is fixed or not supporting auto-negotiation.
