Copper Ethernet Ports
The RUGGEDCOM RSG2300 supports several 10/100/1000Base-TX Ethernet ports that allow connection to
standard Category 5 (CAT-5) unshielded twisted-pair (UTP) cables with either RJ45 male connectors. The RJ45
connectors are directly connected to the chassis ground on the device and can accept CAT-5 shielded twisted-
pair (STP) cables.
WARNING!
Electric shock hazard – risk of serious personal injury and/or equipment interference. If shielded
cables are used, make sure the shielded cables do not form a ground loop via the shield wire and the
RJ45 receptacles at either end. Ground loops can cause excessive noise and interference, but more
importantly, create a potential shock hazard that can result in serious injury.
