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.
Sounds good; known branded equipment is more likely to be compliant - but do check, it’s usually pretty clearly marked on packaging and listings.
