Check the release notes for the version of OcNOS you are using for where to download the IP Infusion Inc. Yang modules for NetConf clients.

Copy the files to /usr/share/yuma/modules/netconfcentral on the host machine where the client application runs. This system path only works with OpenYuma's Yangcli client application. If you are running a different client application, follow the respective reference document to copy the Yang files to the appropriate location.
