Communication Ports
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.
Each port features a Speed and Link LED that indicates the state of the port.
