Product and Software: This article applies to all Aruba Instant platforms and versions 220.127.116.11-18.104.22.168, 22.214.171.124-126.96.36.199, 188.8.131.52-184.108.40.206, and 220.127.116.11-18.104.22.168.
Flash on Aruba Instant APs (IAPs) is segmented into two partitions, which allows IAPs to store a backup image in case an upgrade fails.
When an IAP is migrated from Instant to being managed by a controller, the controller-based AP firmware is stored on partition 0. Partition 1 always retains the IAP firmware. If the hardware reset button on an IAP is activated, the controller-based IAP is restored to Instant mode. The hardware reset button clears the image on Partition 0 and the AP boots with the Instant software image that is on Partition 1.
