For anyone else who may run Extreme K or S series switches with Aruba AP-325 APs, I found the following commands must be run to get the APs to come up to 802.3at power levels:
set port inlinepower *.*.* powerlimit 34000 capability 8023at
set lldp port tx-tlv poe *.*.*
Looks like by default the Extreme switches are set for af power per port
Hope this saves someone else a bit of time and effort when deploying APs
