Power over Ethernet (PoE) switches are network switches that provide both data transfer and electrical power to PoE-enabled devices over a single Ethernet cable. PoE switches are used for powering devices such as wireless access points, IP cameras, VoIP phones, and other network-connected devices.

PoE switches operate by using a technique called Power over Ethernet (PoE) technology, which allows power to be sent along with data on Ethernet cables. This eliminates the need for a separate power supply for each device, simplifying deployment and reducing the cost of the infrastructure.
