Hi Thorsten,
Here is a link to the PAWS-M Admin guide which covers installation (e.g. Get OVA template, Install PAWS-M on separate Virtual Machine, etc.)
http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/pawsm/9_0_1/CUCM_BK_P71BFF78_00_paws-management-administration-guide-90.html PAWS-M ships with Unified CM, so it should have shipped with the NFR bundle. For ordering the NFR bundle, please see details here.
