4.1 Copper Ethernet Ports
The RUGGEDCOM RSG2100 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 or Micro-D male connectors. The RJ45 and Micro-D connec-
tors 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 inter-
ference
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.
Pin-Out
The following are the pin-out descriptions for the RJ45 and Micro-D connectors:
