Introduction To POE Switches

- Feb 26, 2019-

The POE switch port supports output power up to 15.4W or 30W, conforms to the IEEE802.3af/802.3at standard, and supplies power to standard POE terminal equipment through the power supply of the network cable, eliminating the need for additional power wiring. According to the IEEE802.3atPOE switch, the port output power can reach 30W, and the power available to the powered device is 25.4W. Generally speaking, the POE switch is a switch that supports the power supply of the network cable, which can not only realize the data transmission function of the ordinary switch but also simultaneously Power the network terminal.


POE (Power Over Ethernet) refers to some IP-based terminals (such as IP phones, WLAN access points AP, network cameras) without any changes to the existing Ethernet Cat.5 cabling infrastructure. While transmitting data signals, it can also provide DC power for such devices. POE technology can ensure the normal operation of existing networks while minimizing costs while ensuring the security of existing structured cabling.
