What is a Software	You can install an older version of management software on the
Installation?	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.
	3Com recommends that you always run the latest software version on
	the Webcache.
	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.

Installations	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.
