Controller-less WLANs

Product and Software: This article applies to all Aruba Instant platforms and versions 5.0.3.0-1.0.0.0, 5.0.3.0-1.0.0.1, 5.0.3.0-1.1.0.0, and 5.0.3.0-1.1.0.1.

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.
