A PoE switch has the Power over Ethernet functionality built into it. This means you can power devices using network cables. A PoE switch provides power that can be used to run other devices via the Ethernet cabling. If your network has distributed switches, it's also possible to get PoE pass-through switches.
Unlike other traditional power distribution sources, the use of PoE switches consolidate the power distribution on a single source. These switches are universally compatible and can be used to reset or disable devices. Additionally, these switches can be equipped with an uninterrupted power supply.
The PoE switch connections requires no additional cables, because it transmits data and power through the ethernet cable. The devices connected to the switch can be easily repositioned to a new location as per the requirement. The powerful combination of wireless technology and PoE creates a cable-free environment, which assures hassle-free working of devices connected to them.
