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
wallpapers, certificates and favorites list (My contacts).
• The previous (inactive) software image will be deleted.
• Option keys and release 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 system’s log
files and configuration before you perform a factory reset.
It is not possible to undo a factory reset.
There is more information about performing a factory reset in
the ► Factory resetting appendix.
