I have had a few times where support asks me to default APs. I’m working on a network where I expect the APs to provide PoE output to cnWave backhauls. I would really like the AP to have 802.3af PoE turned on by default so factory defaulting an AP doesn’t require a site visit.
I don’t see any specific reason not to do this - I have not had any issues with non-PoE devices having a problem being plugged into PoE switches, so I imagine this would not have any downsides.
The problem is when support asks you to default an AP. Then, you lose power to your cnWave backhaul and it requires a site visit to fix. I suppose if they automatically meshed on Wi-Fi when wired backhaul is down (like UniFi does) that would provide enough communications to reprovision and repower the backhaul.
