There are two main types of PoE: active and passive. Active accounts for about 99% of usage, with common wattage options including 15.4W, 30W, 60W, and 90W. If you’re planning to use PoE, you’ll also need to know the required wattage, and most modern switches now offer around 30 watts per port, while enterprise devices often provide 60W or more per port.
It depends on what provides the power for PoE. It can come from a dedicated injector or the switch itself. Using a switch to inject PoE works well when most devices need it, like security cameras, but it becomes less practical if only a few items require it. There’s room for PoE switches, though they aren’t suitable everywhere. For limited PoE needs, injectors are better, especially if you’re near outlets. I haven’t used PoE for monitoring yet, so I’m unsure of the impact.
