There is no capability to import a device inventory from a spreadsheet. Any in-scope assets will need to be discovered from the RN150, which is the process that builds the Asset Database and ensures those assets can be successfully monitored when licensed. Network and OS firewalls will need to be configured to allow the necessary ports from the RN150 to reach any in-scope assets. Please see our online documentation for pre- requisites: https://docs.flexera.com/foundationcloudscape/help/RCDeployReq.htm
