Installing Embedded Wireless Controller on Catalyst 9000 series APs

[raizo00]

Ordered some C9105AXI-B access points and plan on using the embedded controller without DNA licenses. How do I get that though, is it an image or license I need to download from Cisco?

Was I supposed to buy the one with the part number C9105AXI-EWC-B from the start (wasn’t available at the time) or can that be added later?

I’m new to deploying APs with Cisco to be honest, and never done it before.

Also, does only one of them need to be set as EWC or do all of them?

Need to do a site survey with them too. Does that require a switch?

   You can download EWC image directly from https://www.cisco.com/c/en/us/support/wireless/embedded-wireless-controller-catalyst-access-points/series.html?dwnld=true&dwldImageGuid=658239EAA87B2635D638693939FF9F817765E7FD&atcFlag=N#~tab-downloads

       - The AP may then arrive with CAPWAP based (client image) , you then need to convert it to EWC following the software you downloaded earlier (see first remark) : https://www.cisco.com/c/en/us/support/docs/wireless/embedded-wireless-controller-on-catalyst-access-points/215303-embedded-wireless-controller-conversion.html

    Review this document https://www.cisco.com/c/en/us/products/collateral/wireless/catalyst-9800-series-wireless-controllers/nb-o6-embded-wrls-cont-ds-cte-en.html  and or also the parts related to licensing ,
