RJ-45 Network Ports
RJ-45 Network Ports can connect any networking devices that use a standard LAN interface, such as a Hub/
Switch Hub or Router. Use unshielded twisted-pair (UTP) or shield twisted-pair (STP) cable to connect the
networking device to the RJ-45 Ethernet port. Depending on the type of connection, 10Mbps or 100Mbps,
use the following Ethernet cable, as prescribed.
