are the diameters of the core and the core plus the cladding respectively). Single-mode

fiber allows full bandwidth at longer distances, and may be used to connect 10 MB nodes

up to 10 Km apart, or 18Km with the 6K-SSC.

The same procedures as for multi-mode fiber, applies to single-mode fiber

connectors. Follow the steps listed in Section 3.2.2 above.

3.2.4

Connecting Twisted Pair (RJ-45, CAT3, CAT5, Unshielded or

Shielded)

The RJ-45 ports of the Magnum 6K8-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).

Twisted Pair (CAT 5)

100BASE-TX RJ-45

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 or

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.

4. The auto cross (Auto-MDIX) feature will eliminate the use of crossover cable, while

connecting the RJ-45 ports to any other RJ-45 device.
