CM12 offers several ways to deploy the client on computers. We'll show our favorite method first, Software Update Point (SUP)-based installation, and then show the popular "client push" method. This is our favorite because it allows you to leverage GPO on the client to pull the client installation from the SUP, instead of traditional client push installation, where the server must connect, copy, and remotely start an installation.
You should have a fully functional primary and management point(s) before attempting to install and assign clients. For SUP-based installation, a functioning, active SUP at the primary, to which you intend to assign clients, must be in place.
