Product and Software: This article applies to Aruba Instant AP.
You can convert an Aruba Instant AP (IAP) to a controller-based (thin) AP by using the WebUI on the IAP. Navigate to Maintenance > Convert. Simply populate the IP address within the IAP for the controller you want the AP to communicate with, and it will connect and automatically convert itself.
To restore IAP functionality (from thin mode), you must gain physical access to the IAP and press the reset button on the back of the unit with a paper clip or equivalent tool.
