Was going to buy and return them to get the info I need, but luckily the datasheets had enough resolution to make out the fcc ids.
In case anyone else is looking for them:
ap11 - Q9DAPIN0303
ap12 - Q9DAPIN0304305
ap15 - Q9DAPIN0314315
All qualcomm chipsets and they're built nothing like the enterprise grade counterparts. Pretty disappointed in not only the hardware but the incredible lack of response from support on this forum.
Oh, good catch. Confirms my suspicions that the Instant On APs are re-skins of existing models (those are the IDs of AP-303, AP-305, etc., so I'm not sure what you mean by different than the enterprise models unless I'm missing something): I posted some links at https://community.arubainstanton.com/t5/Instant-On-Wireless/Hardware-comparison-to-other-Aruba-APs/m... that include the datasheets of those enterprise models (interest was the antenna patterns).
