  **12.3.1 Obtaining an encryption license**
  
  You must purchase an encryption license before you activate encryption. If you did not 
  purchase a license, contact an IBM marketing representative or IBM Business Partner to 
  purchase an encryption license. 
  
  When you purchase a license, you receive a function authorization document with an 
  authorization code printed on it. This code allows you to proceed using the automatic 
  activation process. 
  
  If the automatic activation process fails or if you prefer the use of the manual activation 
  process, see this web page to retrieve your license keys. 
  
  Ensure that you have the following information: 
  
  (cid:2) Machine type (MT) 
  (cid:2) Serial number (S/N) 
  (cid:2) Machine signature
