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.

All good answers, one thing not mentioned is that there are smart/managed switches where you can toggle PoE on/off per port on the network switch. Could be useful, sometimes it's best just to never provide power on any network ports until you know you need it.
