Power over Ethernet (PoE)

What is Power over Ethernet (PoE)?

Power over Ethernet (PoE) is technology which carries electricity through data cables. PoE enables devices allow the current to pass through the ethernet cable with the data normally carried by an ethernet cable.

Essentially, you can install one cable instead of running two; the power currant can go over the network cable. So, as long and you have network outlets, you don’t have to use a power outlet for the device. You are reducing the cabling required for network devices.

Devices that use Power over Ethernet (PoE)

Most devices which connect to a network via an ethernet cable such as;

  • IP Phone systems
  • Wireless Routers
  • IP CCTV Systems

Why use POE?

Time and cost savings – less time and cost involved when installing less cables.

Flexibility – devices can be located wherever they are needed rather than constricted to the nearest power supply.

Safety – designed to protect network equipment from overload and underpowering.

Reliability - POE comes from a universally compatible source, rather than a collection of different power cables.

Scalability - having power available on the network means that the distribution of network connections is simple.
