What is POE?
POE stands for Power over Ethernet.
It allows a compatible device to receive both data and power through the same network cable (Ethernet), instead of needing a separate power supply.
This can:
-
Eliminate the need for extra power adapters
-
Free up wall sockets
-
Make installations cleaner and easier, especially in offices or wall-mounted setups
Do I need POE?
That depends on how and where you plan to use your VoIP phones or other networked devices.
POE may be a smart option if:
-
You don’t want to run extra power cables
-
You don’t have power sockets near the phone location
-
You're installing multiple phones in an office
-
You want a tidier setup without separate power bricks
What do I need to use POE?
To use POE, you’ll need one of the following:
Option 1: A POE-capable network switch
-
This is the most common method
-
Only connect POE-compatible devices (like most modern IP phones) to the POE ports of the switch
-
The switch will automatically provide power to the devices that support it
Option 2: A POE injector
-
A small device placed between your network and the device
-
Injects power into the Ethernet cable
-
Often used when you don’t have a POE switch
Note: In many cases, buying a basic power supply for the device may be cheaper than a POE injector, especially if you only need one or two units.
Final tips
-
Check if your phone or device supports POE before ordering, not all models do
-
If you're buying phones in bulk, it may be cheaper long-term to use POE
-
Some devices are sold without power supplies, assuming you'll be using POE, keep this in mind when budgeting
