blinks in succession.
Caution
Do not power down the controller or any mesh access point during this process; otherwise, the software
image may become corrupted. Upgrading a controller with a large number of mesh access points can
take around 30 minutes, depending on the size of your network. The mesh access points must remain
powered on, and the controller must not be reset during this time.

Caution
Controller software release 7.0 is greater than 32 MB; therefore, you must verify that your TFTP server
supports files of this size. Two TFTP servers that support files of this size are tftpd and the TFTP server
within Cisco WCS. If you download the software and your TFTP server does not support files of size
greater than 32 MB, then a TFTP failure while storing in flash error message appears.

to release 7.0 controller software upgrade, ensure that all mesh access points associated with the
controller are at the same intermediate release before preceding to install the next intermediate or final
version of software. In large networks, it can take some time to download the software on each mesh
access point.
