Upgrading to a New Software Release
Upgrading to a New Software Release
When you upgrade the controller’s software, the software on the controller’s associated access points is
also automatically upgraded. When an access point is loading software, each of its LEDs blinks in
succession. Up to 10 access points can be concurrently upgraded from the controller.

succession. Up to 10 access points can be concurrently upgraded from the controller.
Caution
Do not power down the controller or any access point during this process; otherwise, you might corrupt
the software image. Upgrading a controller with a large number of access points can take as long as 30
minutes, depending on the size of your network. However, with the increased number of concurrent
access point upgrades supported in software release 4.0.206.0 and later, the upgrade time should be
significantly reduced. The access points must remain powered, and the controller must not be reset
during this time.

Note
In controller software release 5.2.178.0, the WLAN override feature has been removed from both the
controller GUI and CLI. If your controller is configured for WLAN override and you upgrade to
controller software release 5.2.178.0, the controller deletes the WLAN configuration and broadcasts all
WLANs. You can specify that only certain WLANs be transmitted by configuring access point groups.
Each access point advertises only the enabled WLANs that belong to its access point group. Access point
groups do not enable WLANs to be transmitted on per-radio interface of AP.
