Swapping to POE switch (sh.itjust.works)

I live in a house that has CAT 5 cable in the walls running to wall plates in various rooms.

Would it be possible to remove the existing regular switch, replace it with a powered POE switch, and then plug in a POE device into one of the wall plates?

Also, for the non-POE devices already plugged into wall plates, would they be okay?

I'm trying to wrap my head around the interoperability of POE and non-POE and struggling.

And most importantly, you do NOT want anything that does passive POE, because it puts 48v on one of the pairs, which will zap any equipment not expecting it.
