These are shielded RJ-45 data sockets. They cannot be used as standard traditional telephone sockets, or to connect the unit to a traditional PBX or public telephone network. Only connect RJ-45 data connectors, network telephony systems, or network telephones to these sockets. Either shielded or unshielded data cables with shielded or unshielded jacks can be connected to these data sockets. 10BASE-T/ 100BASE-TX/ 1000BASE-T Ports The Switch has 12 or 24 auto-negotiating 10BASE-T/100BASE-TX/ 1000BASE-T ports configured as Auto MDIX (cross-over). These ports automatically provide the appropriate connection. Alternatively, you can manually set these ports to 10BASE-T half duplex, 10BASE-T full duplex, 100BASE-TX half duplex, 100BASE-TX full duplex, or 1000BASE-T full duplex. The maximum segment length is 100 m (328 ft) over Category 5 twisted pair cable.
