Certificate-Related Files
For troubleshooting purposes, Table 14-1 lists certificate-related files on the Clean Access Manager. For
example, if the admin console becomes unreachable due to a mismatch of the CA-certificate/Private Key
combination, these files may need to be modified directly in the file system of the Clean Access
Manager.
For additional information on Clean Access Manager files, see Cisco NAC Appliance Log Files,
page 13-11.
System Upgrade
In Cisco NAC Appliance Release 4.9 and later, you can perform system upgrades from Release 4.7(x)
and 4.8(x) by uploading a .tar.gz upgrade file to the CAM/CAS and executing an upgrade script using
the appliance’s CLI. For complete upgrade details, including instructions for upgrading HA CASs and
