For phones without a PC port, a separate Gigabit Adapter (SAP 700416985) must be used. This device splits the data and voice traffic before it reaches the phone, providing a 10/100Mbps output for the phone and a 10/100/1000Mbps output for the PC. The adapter is powered from the phone's existing power supply. Refer to the "Gigabit Ethernet Adapter Installation and Safety Instructions" (16-601543).
