HP PoE+ Allotment Question

I am attempting to add more Aerohive APs to a PoE switch. What I am trying to figure out is how HP allocates and distributes the PoE. I cannot seem to find this answer anywhere.

For example: I know that PoE+ devices which require over 15W have a full 30W allocated to them on Cisco PoE+ switches (I may be a bit off on this). If a cisco AP is pulling 24.8W, the excess 5.2W does not count towards the available PoE. If the PoE+ limit is reached (based on multiples of 30), some switchports will default back to 15W. Is this also the case with HP switches?

Model is 2920-48G J9729A

Thank you!
