Symantec Endpoint Encryption Serverless Licensing

I am looking for some information on how licensing works in a serverless enviroment.  So far I have the Management Agent installed on a Windows 7 machine.  I used this to deploy the three client installation files.  During the client installation I wasn't prompted to enter trial license keys.  I don't see anywhere that I can put keys after I purchase the licenses. 

What happens at the end of 30 days? 

Where can I put license keys so the end users aren't prompted at the end of the trial period? 

Is there documentation for how licenscing works in Endpoint Encryption?

I am just looking for some understanding before I purchase and deploy this product.
