Exp: System recovery: Factory reset If there is a severe problem with the video system, the last resort may be to reset it to its default factory settings. Always consider reverting to the previously used software image before performing a factory reset. In many situations this will recover the system*.
A factory reset should only be performed by a system administrator or in contact with Cisco technical support. When factory resetting the video system the following happens:
The call logs will be deleted.
Passwords will be reset to default.
All system parameters will be reset to default values.
All files that have been uploaded to the system will be deleted. This includes, but is not limited to, custom backgrounds, certificates, and the favorites list (My contacts).
The previous (inactive) software image will be deleted.
Release keys and option keys will not be affected. The system restarts automatically after the reset. It is using the same software image as before. We strongly recommend that you backup your systems log files and configuration before you perform a factory reset.
