Copper Ethernet Ports
The RX1100P supports several 10/100Base-TX Ethernet ports that allow connection to standard Category 5
(CAT-5) unshielded twisted-pair (UTP) cables with 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.
The RX1100P also comes standard with two 10/100Base-TX IEEE 802.3af (PoE)-compliant Ethernet ports in Slot
3 (2 ports), and can accommodate two more in Slot 4. In addition to the 10/100BaseTX port features, the PoE
ports provide nominal 48 VDC at 350 mA (max 15.4W/port), with auto-sensing and automatic power off when
cables are removed.
Each port features a Speed and Link LED that indicates the state of the port.
