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
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 6K25e. 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 6K25e passes the
1613specifications for zero packet loss with fiber ports & with RJ45 ports used
as indicated here.
3.2.5 Connecting Twisted Pair (CAT5E or better, Unshielded or Shielded)
The RJ-45 Gigabit ports of the Magnum 6K25e 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 maximum distance for unshielded twisted pair cabling is 100 meters (328
ft). See Section 4.3 for manual Up-Link switch on port 1 of copper port modules.

Twisted Pair (CAT 5E) 1000BASE-T RJ-45
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
