Magnum 6K8-Series Industrial Field Switch             Installation and User Guide   (04/07) 
NOTE:  for Power Substations:   In support of the IEEE 1613 Class 2 standard, GCI 
advises that, for substation applications, the RJ-45 ports are intended for connectivity to 
other communication equipment such as routers or telecommunication multiplexers 
installed in close proximity (i.e., less than 2 meters or 6.5ft) to the 6KQ. It is not 
recommended to use these ports in substation applications to interface to field devices 
across distances which could produce kigh (greater than 2500V ) levels of ground 
potential rise (GPR) during line-to-ground fault conditions. The 6KQ passes the 
1613specifications for zero packet loss with fiber ports & with RJ45 ports used as 
indicated here.

Connecting Twisted Pair (CAT5E or better, Unshielded or 
Shielded) 
The RJ-45 Gigabit ports of the Magnum 6K8-Series can be connected to the 
media types, 1000BASE-T or CAT 5E or better 100-ohm UTP or shielded twisted pair 
(STP) balanced cable.  The CAT 5E or better 100-ohm UTP or shielded twisted pair 
(STP) balanced cable is recommended to use when making 1000BASE-TX connections.   
In either case, the max distance for unshielded twisted pair cabling is 100 meters (328 ft).

NOTE :   It is recommended that high quality CAT. 5E cables (which work for both 100 
Mb and 1000Mb) be used whenever possible in order to provide flexibility in a 
mixed-speed network.
 
The following procedure describes how to connect a 1000BASE-T twisted pair segment 
to the RJ-45 port. The procedure is the same for both unshielded and shielded twisted 
pair cables. 
1.    1000Base-T connections require that all four pairs or wires be connected.  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
