PoE switch provides PoE power to network devices such as access points, surveillance cameras, IP phones, lighting, and other IoT devices. PoE switches often are capable of prioritizing and optimizing PoE power allocations for critical network devices. By eliminating the need for separate data and power cables, PoE provides the advantages of simplicity and cost savings, while adding new intelligent device control capabilities. Driven by the need to connect emerging power hungry IoT devices, PoE technology has progressed with the introduction of the IEEE 802.3bt standard. This new standard allows PoE switches and powered devices to operate above 30 Watts of PoE per port and support up to 60 and even 90 Watts of PoE per port.
