What is Power Over Ethernet (PoE)?
Power over Ethernet or PoE is a cost effective solution that allow both data and power to be provided over an (or same) ethernet cable to an endpoint.
Why use Power Over Ethernet (PoE)?
There are a number of reasons why you would use PoE, but in most cases the overriding reason is cost and easy of install.
For an example: It can cost between $100 and $200 to run an ethernet cable to a wireless access point. But it can costs a further $400 to run an electrical conduit to power that access point . This will combine the data and power at the source to be sent through the ethernet cable. The power from the cable can then be extracted at the endpoint with a Powered Device (PD) to operate the access point. This solution removes the need to run expensive electrical conduit and will cost considerably less than $400.
Allied Telesis PoE Power over Ethernet switches are ideal for applications using security cameras, wireless access points, IP phones or any PoE device. All ports are equipped with an internal power supply and built with a robust metal chassis. One SFP port connects this device to other switches in your network. Fully auto-configuring, auto-negotiating and Auto MDI/MDIX, this switch requires minimal set-up.
