Carlos;
You will want to review this link for initial configuration of the AIP-SSM:
http://www.cisco.com/en/US/docs/security/ips/7.0/configuration/guide/cli/cli_ssm.html
The module itself will need an IP address for remote access/management, the host ASA will need a service policy to divert traffic of interest to the AIP-SSM for inspection, and you will want a valid license on the AIP-SSM so you can update the detection signatures.
