To add the systems you have to execute the "Basic Conifguration" and the "Managed System Configuration" in Solution Manager transaction SOLMAN_SETUP.
This will connect the systems with Solution Manager.
There are tools within Solution Manager to get some guidance on which notes to implement (e.g. security notes) in the satellite systems.
However, as others already mentioned, the actual implementation is done in the systems and not in/via Solution Manager.
