7 The software upgrade may take several minutes to complete. The 

Software Upgrade Successful screen is displayed when the software 
upgrade has been successful.

8 Click OK to exit the Upgrade Software wizard and reboot the Webcache. 

This will complete the software upgrade. The Device View is displayed in 
the Web interface.

You can install an older version of management software on the 
Webcache than the version that is currently running. This is useful in the 
unlikely event that you are experiencing problems following a software 
upgrade of the Webcache. A software installation should only be 
performed as an emergency recovery procedure.

CAUTION: Unlike a software upgrade, all of the Webcache’s 
configuration settings are lost after a software installation has been 
completed; the Webcache is reset to its factory defaults. For more 
information, see “Default Settings” on page 22. To restore the settings 
after the installation is complete, you must restore a system configuration 
file that you have previously saved. This configuration file must have been 
saved on the same software version as the software that you have just 
installed. For more information, see “Saving and Restoring 
Configurations” on page 103.

The Webcache software installation process is robust and guards against 
an installation failure. Should a software installation fail, the Webcache 
will automatically revert to using the software version that was installed 
before the installation was started. The installation process is resilient to 
power failure, network failure or system failure.

To install an older version of management software using the Web 
interface:

1 Log in to the Web interface.

2 Click Device View on the Toolbar.
