local mode -> EWC mode

Hello

9115AP
IOS Version 17.9.4.27 (Recommended Version)
I have a 2 questiAs

far as I know, the original EWC-AP configuration is changed to EWC-mode after 3 minutes after booting to local mode, so it asks automatic configuration questions.on about.

Is there a command that can be manually changed to EWC mode?

One more question is that I rebooted after setting up EWC mode, but it went back to Backup image. I looked it up and found that if I don't find the existing IOS image, it will boot and go back to Backup Ios, is there a command to fix IOS?

I noticed that even if I tried to change to ewc mode, I needed a tftp server.

EWC image: When an EWC image is installed on an access point, it can operate as both a controller and an access point or as an access point alone.

To determine the image and capability on the access point, you can do a show version command on the AP CLI to determine the AP image type and AP configuration:

If the show version command does not display the AP image type and AP configuration parameters, it means the AP is running the CAPWAP image.

If the show version command displays the AP image type as EWC IMAGE and the AP configuration as EWC CAPABLE, it operates as both a controller and an access point. It participates in the active election process in case of a failover.

If the show version command shows the AP image type as EWC IMAGE and the AP configuration as NOT EWC CAPABLE, it operates only as an access point and does not participate in the active election process in case of a failover.

The following is sample input from the show version command:
