Diagrams and descriptions of the four different ways that your VOIP phone and computer may be connected to power and internet.
Overview
There are four different configurations LITS uses to connect Avaya VoIP phones and office computers to power and internet. These are explained below.
Is my phone plugged in correctly?
When you flip your Avaya VoiP phone over, you'll see five main ports that each have distinct purposes. Looking at the phone upside down, the ports will be in the following order from left to right: Power, Network, Computer, Headset, Phone handset. These are explained in more details in the table below.
| Symbol |
Purpose |
| Power -- |
If you don't have a "power over ethernet" port, then your phone will need a power cord to be on. That cord gets plugged in to this port. |
| Network |
The other end of the ethernet cable plugged in here should be plugged into an ethernet port on the wall. This will connect the phone to the network enabling it to make and receive calls. |
| Computer |
If you're connecting a computer to wired internet and only have one ethernet port on the wall, you can plug your computer's ethernet cable in here to "daisy chain" the internet connection from the wall to your phone to the computer. |
| Headset |
If you have a headset to use with your phone, you would plug it in to this port. |
| Phone handset |
The phone's handset should be plugged in to this port. |
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.
Separate ethernet cables without power over ethernet
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.
Daisy chain without power over ethernet
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.
