PoE switch (Power over Ethernet switch) What is a PoE switch (Power over Ethernet switch)?
Power over Ethernet (PoE) is an access layer technology that combines data signals and electrical power into a single Ethernet cable connection, delivering both to enable a powered device (PD). A PoE switch provides power and network connectivity over Ethernet cables to access points, security cameras, and other Internet of Things devices (IoT).

A PoE Switch explained
Power over Ethernet (PoE) is an access layer technology that combines data signals and electrical power into a single Ethernet cable connection, delivering both to enable a powered device (PD). PoE runs over twisted pair Ethernet cabling, which can be installed quickly, often in difficult to reach locations where pulling electrical power from an outlet is not feasible. Power Sourcing Equipment (PSE) use PoE technology to supply power to a device. In a local area network, the role of PSE frequently goes to a PoE switch.
The purpose of a PoE switch is to deliver power and network connectivity over Ethernet cables to access points, security cameras, IP phones, PoE lighting, and other Internet of Things devices (IoT) wherever they are deployed.
