Cisco Cisco Secure Access Control System 5.1 Documentation Roadmaps

This document provides important license and documentation information for the Cisco Secure Access 
Control System 5.1 (ACS), a centralized network identity and access control system.

A Product Authorization Key (PAK) for each Cisco Secure ACS 5.1 that you purchase is affixed as a 
sticky label at the bottom of the Software License Claim Certificate card included in your package. 
Carefully follow the instructions on this card to perform customer registration via the Internet. You must 
submit the PAK that you received to obtain valid license file(s) for your system. For each PAK that you 
submit, a license file is generated and sent to you via email, which you should save to disk. You must 
install these license files on your Cisco Secure ACS later.

To obtain the latest Cisco Secure ACS software release, log in to the Cisco Software Download Site at 

 and navigate to Security > Identity Management 

> Cisco Secure Access Control System > Cisco Secure Access Control System 5.1.
