Understand campus VOIP telephone cable setups

Overview

There are four different configurations LITS uses to connect Avaya VOIP phones and office computers to power and internet. These are explained below.

Separate ethernet cables with power over ethernet

When 2 ethernet jacks are available, and at least one of them offers power over ethernet, we can connect the phone to both power and internet with one ethernet cable to the powered jack. In this setup, the computer is connected to internet via a second ethernet cable to the wall and powered via its own power cable.

When 2 ethernet jacks are available, and none of them offer power over ethernet, we can connect the phone to one jack via an ethernet cable and the computer to the other jack via a separate ethernet cable. In this set up, the phone and the computer each have their own power cable to the wall.

Daisy chain with power over ethernet

If there is a powered ethernet jack, we can connect the phone to both internet and power with a single ethernet cable. In this setup, the computer is connected to the internet via an ethernet cable to the phone and powered with its own power cable.

In cases where there is just one ethernet jack that is not powered, we can connect the phone to the ethernet jack with an ethernet cable. In this setup, the phone also needs its own power cable to the wall and the computer connects to the internet via an ethernet cable to the phone.
