Connecting Ethernet Media 

The Magnum 4K220 Switches are specifically designed to support  twisted pair 
Ethernet media. The media types supported along with the corresponding IEEE 802.3 
and 802.3u standards are as follows:

IEEE Standard        Media Type            Max. Distance       Port Module

      Copper:

10BASE-T & 100BASE-TX twisted pair  100m (328 ft) 

RJ45 

3.2.1 

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

Shielded)

The RJ-45 ports of the Magnum 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).

Media 

IEEE Standard          Connector 

Twisted Pair (CAT 3, 4, 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 

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.
