On the back or bottom of your phone, find the port labeled "Internet" and plug in a network cable. Connect the power adapter (DC 5V) into the round port labeled "DC/Power" (some phone models do not require dedicated power).
Plug into the wall
Plug your network cable into your ethernet/network outlet. Plug the power adapter (DC 5V) into a standard wall outlet. (Employees working from home may not have an internet cable connecting to the wall if they are using Wi-Fi.)
