Copper Ethernet Ports
The RUGGEDCOM RS910W supports multiple 10/100Base-TX Ethernet ports that allow connection to standard
Category 5 (CAT-5) shielded or unshielded twisted-pair cables with RJ45 male connectors.
WARNING!
Electric shock hazard – risk of serious personal injury and/or equipment interference. When 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.
