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.

Note
The Cisco 5500 Series Controllers can download the 6.0.199.0 software to 100 access points
simultaneously.
simultaneously.
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 releases, 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 or later releases, 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 6.0.196.0, 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.
