Explanation:
Detailed explanation-1: -Power of Ethernet (PoE) is combining power and data communications in a single cable. As it’s become more and more popular, there are a huge array of devices that source and consume power and data through the same cable. Do all Ethernet cables support PoE? No, they don’t.
Detailed explanation-2: -As described above, standard PoE can supply maximum power output of 15.4W, while PoE+ is 30W. When a plan calls for multiple devices to be connected to one PoE/PoE+ switch, it’s necessary to ensure the total wattage required by the devices does not exceed the maximum wattage of the switch.
