What is the difference between POE switches and ordinary switches?

POE (Power Over Ethernet) refers to some IP-based terminals (such as IP phones, wireless LAN access points APs, network cameras) without any changes to the existing Ethernet Cat.5 cabling infrastructure. Etc.) While transmitting data signals, it is also possible to provide DC powered technology for such devices. POE technology can ensure the normal operation of existing networks while ensuring the safety of existing structured cabling, and minimize costs.

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