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. |
Unsuccessful | The Webcache software installation process is robust and guards against |
Software | an installation failure. Should a software installation fail, the Webcache |
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. |
