Understanding Power Consumption of PoE Ethernet Switch 1

Understanding Power Consumption of PoE Ethernet Switch

As PoE changes to meet today’s increasing application requirements like IP cameras or WiFi access points, it’s widely used for enterprises networks. Using a PoE or PoE+ switch, technicians can simplify the cabling installation because the PoE technology can support power and data transmission over the same cables. When choosing a PoE Ethernet switch, we always care about the ports and power…
