2. Download the Appliance "upgrade nac_appliance_64bit_sw_upgrade_to_<version>.bin" file from extranet.extremenetworks.com and copy it to the NAC Appliance.
The "<version>" in the above file name is a place-holder for this example, and will change from revision to revision.

3. SSH into the NAC Appliance

4. Change permissions on the file to make it executable

chmod u+x nac_appliance_64bit_sw_upgrade_to_<version>.bin

5. Run the install program

./nac_appliance_64bit_sw_upgrade_to_<version>.bin

6. After the upgrade completes, the SSH session will return to the command prompt

7. Trigger an "Enforce" from NAC Manager or the Control > Access Control section of the Extreme Management Center GUI.
