Media Converter Switches Installation and User Guide

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.
3.8.1 Connecting 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.
1. Using standard twisted pair media, insert either end of the cable with a RJ-45 plug
into the RJ-45 connector of the port. Note that, even though the connector is shielded,
either unshielded or shielded cables and wiring may be used.
2. Connect the other end of the cable to the corresponding device.
3. Use the LINK LED to ensure proper connectivity by noting that the LED will be
illuminated when the unit is powered and proper connection is established. If this
does not help, ensure that the cable is connected properly and that the device on the
other end is powered and is not defective.
