Magnum 10KG Managed Switch Installation and User Guide
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 10KG. It is not
recommended to use these ports in substation applications to interface to field devices
across distances which could produce high (greater than 2500V ) levels of ground
potential rise (GPR) during line-to-ground fault conditions. The 10KG passes the 1613
specifications for zero packet loss with fiber ports & with RJ-45 ports used as indicated
here.
Connecting Twisted Pair (CAT5e or better, UTP or STP)
3.2.2
The RJ-45 Gigabit ports (Slots A,B,C and D) of the Magnum 10KG 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).
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
LASER WARNING: DO NOT LOOK INTO A FIBER OPTIC
CABLE OR PORT! These can produce invisible light that may do
serious eye damage. Always assume that fiber optic cables or ports
are actively radiating light energy.
Connecting Singlemode Fiber Optic
3.2.3
When using singlemode fiber cable, be sure to use singlemode fiber port
connectors. Singlemode fiber cable has a smaller diameter than multimode fiber cable
(9/125 microns for singlemode, 50/125 or 62.5/125 microns for multimode where xx/xx
are the diameters of the core and the core plus the cladding respectively). Singlemode
fiber allows full bandwidth at longer distances, about 70km with the singlemode LC.
