When we talk of power over Ethernet it is with reference to a technology that allows network cables to transfer electrical power. For instance, a digital security camera requires two kinds of connections to be made, a network connection and a power connection. If it is enabled by the power over Ethernet technology, it will receive electrical power from the cables that provide network connections.
The advantages of power over Ethernet
There are several advantages that POE Ethernet switch brings about in different installations. For instance, costs as well as time are saved as electrical cabling is not required. Network cables on the other hand, are easier to fit and install and do not require a licensed or qualified electrician to install the same. Devices like IP cameras need not be attached to an electrical outlet when harnessed with this technology. Wireless access points are easily located anywhere and can be repositioned as required. The delivery of POE is intelligent and protects network equipment from power overload as well as damages that can occur from incorrect installation or under powering. POE power usually comes universally compatible. It can have uninterrupted power supply, easily controlled by reset or disable devices. Visit http://www.fortronixmart.com/pd/power-over-ethernet/
Devices that use power over Ethernet
There are several devices that straddle this technology these days. POE has key application areas like VoIP phones which have a single connection from a wall socket or could be powered remotely. IP cameras or network surveillance cameras use such technology that allows repositioning more easily as well as deployment. Wireless devices like RFID readers are also made POE compatible that allows them to be used in remote locations which might be away from AC outlets.
Upgrading to power over Ethernet
POE network creation is easy. This is done by either a POE switch as in a industrial media converter fiber optic. POE switches are network switches that have POE injection built into them. All you need to do is connect to different network devices as required and the switch detects which devices are POE compatible. They enable power to these devices in an automatic way.
POE switches are usually devised to suit different applications. These could be unmanaged edge switches that are low cost or could be complex rack mounted units that are multi port in nature. If you wish to make use of POE switches for an existing network and get expert help, there are many specialists in network systems and connections that can provide the necessary equipment or make the changes to give you the advantage of a simpler network and electrical setup.
