The actual Instant code is not release yet, so you would need to get it first. From there, you would stand up the UAP (AP-367) on a vlan that doesn't have a controller, no other IAPs, and a network that doesn't have DHCP option 43/60 or a dns entry for aruba-master (if your site has a controller). Once it comes up and doesn't find an instant cluster and no controller, it will broadcast a provisioning SSID. You can connect to that and then upload the IAP code.
What region are you in (country, region/state, area, etc) and I can loop in your local account team to help you since you got some product before the code was released (you can IM it to me if you need to). Thanks
