NOTE: When you distribute software from NM Portal to enrolled APs, the software
distribution retries three times on each of the APs selected. Some management services
on the NM Portal AP are shut down to make room for the new image distribution. The
NM Portal AP runs through entire list of selected APs before it restarts management
services. Therefore, it is best to perform software distribution when it is least disruptive
to the network. Each AP upgrade can take up to two to three minutes.
Since NM Portal restarts services only after distribution is complete, you must explicit
reboot the NM Portal if software distribution is interrupted.
CAUTION: Do not leave the Software Upgrade panel while download is taking place.
If you click on another menu item during download, the download process is canceled.
