Downloading Cisco NAC Appliance Software
You can access the latest versions of the Cisco NAC Appliance Release 4.8(x) installation .ISO file as
follows.
Caution
Before downloading or installing any Cisco NAC Appliance software, make sure to refer to the Release
Notes for Cisco NAC Appliance, corresponding to your latest Cisco NAC Appliance release version, to
understand the enhancements, caveats, and upgrade impact to your existing deployment.
Step 1
Log in to the Cisco Software Download Site at http://www.cisco.com/public/sw-center/index.shtml . You
will likely be required to provide your CCO credentials.
Step 2 Navigate to Security > Endpoint Security > Cisco Network Access Control > Cisco NAC Appliance

Step 3
Download the latest 4.8(x) .ISO image (e.g. nac-4.8-K9.iso ) and burn the image as a bootable disk to a

Cisco recommends burning the .ISO image to a CD-R using speeds 10x or lower. Higher speeds can
result in corrupted/unbootable installation CDs.
