Summary
The conflict level is pretty much reduce by the previous
recommendations
Compliant 802.3at PSE is the one with 51V minimum
Physics allow to support most of the higher power classed even
with 44V ((enhanced classification part A group). which is built in
benefit however it doesn't concerns the other standard
requirements nor affect it.
It is perfectly OK that Switch/PSE is 802.3at compliant as long as
its Power Supply supports 51V.
If PSE PS Power Supply is 44V, then 802.3at PSE is not compliant
but working and covered most of high power classes
