what is poe switch

A PoE (Power over Ethernet) switch is a device that combines data signals and electrical power into a single Ethernet cable connection, allowing it to provide power to connected devices such as VoIP phones, wireless access points, and IP cameras. This eliminates the need for separate power cables and is particularly useful in locations where power outlets are scarce. PoE switches can be cost-effective, energy-efficient, and offer flexibility in network deployments. They are available in both unmanaged and managed versions, with the latter providing advanced features for precise network management
