Performing AP Software Maintenance

When a new version of AP software becomes available, you can install it from the controller. You can configure each AP to upload the new software version either immediately, or the next time the AP connects to the controller. You can also set up a maintenance cycle for specific APs using the options available on the AP Maintenance Cycle tab. Part of the AP boot sequence seeks and installs its software from the controller.

Warning

Never disconnect an AP from its power supply during a firmware upgrade. Disconnecting an AP from its power supply during a firmware upgrade may cause firmware corruption rendering the AP unusable.

You can modify most of the radio properties on an AP without requiring a reboot of the AP. During upgrade, the AP keeps a backup copy of its software image. When a software upgrade is sent to the AP, the upgrade becomes the AP's current image and the previous image becomes the backup. In the event of failure of the current image, the AP runs the backup image.
