A PoE switch is a device that combines the functionality of a switch and a power source in one. It has multiple Ethernet ports that can be used to connect other devices, such as VoIP phones, wireless access points, and IP cameras. While PoE doesn't add Ethernet data capabilities, it does offer expanded options for how and where Ethernet end devices can be.

Every PoE switch port requires a higher first-buy purchase cost when compared to an equivalent standard Ethernet switch port. For example, the common 5-port POE switch usually costs 200-300 yuan; The price of POE switches with 24 or even 48 ports will significantly increase, ranging from over 1000 yuan to several thousand yuan. Performance can be an issue in larger high traffic environments, which drives the price up just like a PC that is high performance drives the price up. The main reason some Ethernet switches cost significantly more is because of their advanced networking features, superior build quality, enhanced reliability, specialized industry standards, and high-capacity performance designed for demanding enterprise environments.
