About the previously used 
software image
If there is a severe problem with the video 
system, switching to the previously used 
software image may help solving the 
problem. 
If the system has not been factory reset 
since the last software upgrade, the 
previously used software image still 
resides on the system. You do not have to 
download the software again.
We recommend you to back up the log files and configuration 
of the video system before you swap to the previously used 
software image.
Back up log files and system configuration
1.  Select the Backup tab.
2.  Click Download Logs and follow the instructions to save the 
log files on your computer.
3.  Click Download Configuration Backup and follow the 
instructions to save the configuration file on your computer.
Revert to the previously used software image
Only administrators, or when in contact with Cisco technical 
support, should perform this procedure.
1.  Select the Software Recovery Swap tab.
2.  Click Switch to software: cex.y.z..., where x.y.z indicates the 
software version.
3.  Click Yes to confirm your choice, or Cancel if you have 
changed your mind.
Wait while the system resets. The system restarts automatically 
when finished. This procedure may take a few minutes.
