The SSL certificate has very limited information on MOL. However, here the process that should be followed:
1 - complete the Web Certificate with the company details and the FQDN and select generate certificate
2 - copy and paste the text that is generated into notepad.
3 - send this to a CA to get a signed certificate
4 - import the signed certificate back into the MSL
However, for the MBG and AWC, there is an extra step to consider, as the MBG can act as a proxy and the AWC has two FQDN's, then when making the request to the CA, you need to add a 'Subject Alternate Name' with all the FQDN's the proxy will handle and for the AWC the second FQDN.
I hope this help.
