3.2 Connecting Ethernet Media, and Special Strain-relief feature
Note – see also “Cable Strain Relief Feature, Section 3.4.
The Magnum P62-Series Ethernet Switches (P62F model illustrated here) can be
connected to the following three
media types: 100BASE-TX,
10BASE-T and 100BASE-FX.
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). For
fiber port 100BASE-FX multi-
mode, 50/125 or 62.5/125 microns
cabling can be used, whereas for single-mode, 9/125 microns cabling should be used. Fiber
cabling supports much longer cable distances and higher bandwidth than copper wiring.
Media IEEE Standard
Connector
Twisted Pair (CAT 3 or 5) 10BASE-T RJ-45
Twisted Pair (CAT 5) 100BASE-TX RJ-45
Fiber (Multi-mode) 100BASE-FX SC
Fiber (Single-mode) 100BASE-FX SC
NOTE 1. : 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-sensing function does not sense the cable type.
NOTE 2. It is recommended that to fulfill the requirement of UL2043 smoke tests, the cable (RJ-
45, Fiber, AC/DC power cable) provided by the user must be rated as UL2043
Compliant, for use in air handling and above-the-ceiling spaces.
3.2.1 Connect Twist Pair (RJ-45, CAT 3 or CAT 5, Unshielded or Shield)
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.
