Product and Software: This article applies to all Aruba controllers and ArubaOS versions.
Due to major functional and architectural enhancements in the 220.127.116.11B04 firmware, a direct upgrade from firmware 1.x versions to firmware A80_18.104.22.168B04 versions is not possible. An intermediate upgrade step (to version A80_22.214.171.124b05) must be taken to prepare the system for the upgrade to A80_126.96.36.199B04.
Sometimes after the code upgrade, the A and the G radio MAC address change to FF-FF-FF-FF-FF-XX.
If this change happens to the MAC address, the AP-80 must be reset to the factory default settings, or the hardware must be replaced using the RMA procedure.
