Can’t find the answer I’m looking for online, so I’m gonna see if I can get some help here. Im trying to find the best way to power a poe injector for a small 6u rack. Should I use a regular plug in DC adapter, or use an actual DC power supply? What is the proper and best way to power them while staying small and not expensive. I can also leave the power block part out of the rack to help keep heat down. Lots of options. Some photos or links to some sample products would help me be able to search it.
