PoE issues with N1548P

Hi,

I have a N1500 stack running. In the stack Sw1 is a 1548P with a MPS connected. This switch has several APs connected. I get the following error in the log:

POE[PoE Req]: hpc_poe_pwrdsne.c(4474) 1168935 %% WARN Please configure Power Managementmode to Class Based for 802.3at devices

I have configured Power Management Mode to Dynamic. Is a thought this would allocate the needed power to each connected port? This is my output from Show power inline:
