3.2.4 Connecting Twisted Pair (RJ-45,CAT3, CAT5, Unshielded or Shielded)
The RJ-45 ports of the RFL 3000 4K-Series can be connected to the following
two media types: 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).

NOTE : It is recommended that high quality CAT. 5 cables (which work for both 10 Mb
and 100Mb) be used whenever possible in order to provide flexibility in a mixed-
speed network, since dual-speed ports are auto-sensing for either 10 and
100Mb/s.
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 an 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.
3.3 Rack-mounting
Installation of a RFL 3000 4K24 Switch in a 19” rack is a simple procedure. The
units are 1U (1.70”) high. When properly installed, the front-mounted LED status
indicators should be in plain view and easy to read. Rack-mount installation requires
special “19” rack-mounted brackets and screws (included with each 4K24 unit). The
brackets attach to the front sides of the Switch, which is then fastened into a standard 19”
RETMA rack.
