Upgrading Cisco NAC Appliance Software
Cisco NAC-3300 Series appliances are preloaded with a default version of the Cisco NAC Appliance
software, which may not match the latest release of the software. Cisco recommends that you run the
latest supported version of the system software to ensure you have the latest product enhancements
and fixes.
Note
Cisco NAC Appliance Release 4.5 (and later) only supports and can only be installed on
Cisco NAC Appliance CCA-3140, NAC-3310, NAC-3350, NAC-3390, and NME-NAC-K9
(NAC network module) platforms.
To upgrade Cisco NAC Appliance to the latest supported software version, you can either upgrade
your appliance via script or perform fresh CD installation of the latest Cisco NAC Appliance software
on your machines.
To upgrade any of the appliances, you can download and run the standard product upgrade file (e.g.
cca_upgrade-4.5.0-NO-WEB.tar.gz
). The upgrade mechanism automatically determines whether the
machine is a Clean Access Server or a Lite/Standard/Super Clean Access Manager, and executes
accordingly. For step-by-step upgrade instructions, refer to the “Upgrading” section of the
Release
Notes for Cisco NAC Appliance, Version 4.5(1)
at
http://www.cisco.com/en/US/products/ps6128/prod_release_notes_list.html
.
Starting from release 4.5, there is only one product installation CD (
nac-4.5_0-K9.iso
) for all appliance
platforms. The installation package determines whether the Clean Access Server, Clean Access
Manager, or Super Clean Access Manager was previously installed, as well as the previous software
version. See Installing Software via CD on Cisco NAC Appliance, page 28 for further details.
