PoE (Power over Ethernet) Switch allows networks switch to transmit both power and data for IP- based terminals (such as wireless AP, VoIP phone, and IP camera) through an Ethernet cable at the same time. PoE optimizes the installation of powered devices (PDs) and power management, which saves your money and makes installing or expanding a network much simpler.
What is Power over Ethernet?
Power over Ethernet (POE) is a technology that lets network cables carry electrical power.
For example, a digital security camera normally requires two connections to be made when it is installed:
A network connection, in order to be able to communicate with video recording and display equipment
A power connection, to deliver the electrical power the camera needs to operate
However, if the camera is POE-enabled, only the network connection needs to be made, as it will receive its electrical power from this cable as well.
What are the benefits of PoE Powered Switch?
Because PoE allows you to use one cable for both power and data transmission, PoE saves you money on purchasing and running cable for networking equipment and VoIP phones.
PoE makes installing or expanding a network much simpler and cheaper in buildings where it is too expensive or inconvenient to install new power lines.
Using PoE lets you mount devices in places where it would be impractical to install power, such as drop ceilings.
Using PoE can reduce the number of cables and electrical outlets needed in a crowded equipment room or wiring closet.
Where can use the Power over Ethernet?
POE has many applications, but the three key areas are:
VoIP phones - the original POE application. Using POE means phones have a single connection to a wall socket, and can be remotely powered down, just like with the older analog systems.
IP cameras - POE is now ubiquitous on networked surveillance cameras, where it enables fast deployment and easy repositioning.
Wireless - Wifi and Bluetooth APs and RFID readers are commonly PoE-compatible, to allow remote location away from AC outlets, and relocation following site surveys.
Unipoe's POE switch support 802.3at (single port max 32W), and 802.3af (single port max 15.4W) PoE standard , Some of models support 60W ultra power for single port(802.3bt standard). POE powered gigabit switch can automatically detect and recognize the class of PD device, more intelligent to supply power. They won’t be burning out the passive PoE device.
