Power over Ethernet (PoE) is a technology that enables the electrical current necessary for operating each device to be carried by Ethernet data cables instead of standard electrical power cords and wiring. PoE allows network cables to carry electrical power, eliminating the need for separate power supplies and outlets. The main advantage of PoE is that it reduces the cabling requirements for network devices, making installation simpler and less expensive. PoE technology offers several benefits, including:
-
Cost savings: PoE eliminates the need for AC/DC power supplies and outlets to give power to PD equipment, lowering the costs of adding or installing compatible PD equipment since you don’t need an electrician to install power if there isn’t any where you want to place your new PDs.
-
Flexibility: PoE connections offer greater flexibility in terms of where you can locate a device, as you are not dependent on mains plug sockets or other power sources. This also offers benefits in terms of reliability and safety – power comes from a single, stable source, rather than a variety of.
-
Scalability: Having power available on the network means that installation and distribution of network connections is simple and effective.
PoE is commonly used to power devices such as wireless access points, IP security cameras, VoIP phones, and LED lighting.
