RuggedCom RS900L manual RJ45 Ethernet Ports, RJ45 port pin-out and LEDs

3.2 RJ45 Ethernet Ports

The RS900L has several 10/100Base-TX ports that allow connection to standard Category 5 (CAT-

5)unshielded twisted-pair (UTP) cable with RJ45 male connectors. The RJ45 receptacles are

directly connected to the chassis ground on the unit and can accept CAT-5 shielded twisted-pair (STP) cables. If shielded cables are used, care must be taken to ensure the shielded cables do not form a ground loop via the shield wire and the RJ45 receptacles at either end. The figure below shows the shows the RJ45 port pin-out and LEDs.
