After your certificate has been issued like the majority of server systems you will install your SSL certificate on the same server where your Certificate Signing Request (CSR) was created. This is because your private key will always be left on the server system where the CSR was originally created. It will be either in the application or left somewhere on a directory and path you choose when you generated the CSR. Your SSL certificate will not work without this private key file.
If you do not see your server listed perform a search, or you may have to contact your server vender or hosting provider for best practices on how to install a SSL certificate on your system.
