Upgrading Controller Software

When a controller is upgraded, the code on its associated access points is also automatically upgraded.
When an access point is loading code, each of its lights blinks in succession.
In release 4.0.206.0, up to10 access points can be concurrently upgraded from the controller.
Note
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, the upgrade time should be significantly
reduced. The access points must remain powered, and the controller must not be reset during this time.
Cisco recommends the following sequence when performing an upgrade:
