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.
Good answer.
Just chipping in to point out that there are a LOT of products listed as “POE” that don’t comply with any official standard, and are just designed as a single pair for lower end devices. So to echo your advice, do check for standards before buying.
The idea was to swap in a Ubiquity POE switch so i could power a Ubiquity AP and some POE cameras throughout the house
Sounds good; known branded equipment is more likely to be compliant - but do check, it’s usually pretty clearly marked on packaging and listings.
