40 CHAPTER 4: CONFIGURING THE SWITCH ■ To reload configuration settings that you previously saved to a file, scroll down the page, and then click Browse to locate the backup file on your computer, and then RESTORE to copy the configuration back to the Switch. For security purposes, restoring the configuration does not change the password. ■ If you want to reset the settings on your Switch to those that were loaded at the factory, click RESET. You will lose all your configuration changes. The Switch LAN IP address will revert to the default IP address 169.254.x.y. (see "Automatic IP Configuration" on page 29). You may need to restart your computer to re-establish communication with the Switch. Upgrading the System Software The Upgrade facility allows you to install on the Switch any new releases of system software that 3Com may make available. Newer versions of software can be downloaded via HTTP and copied to the Switch; the Switch will restart and apply the newer system software version. Figure 26 Upgrade Screen Once you have downloaded the software, use the Browse button to locate the file on your computer, and then click Apply. You may need to change the file type in the dialog box displayed by your Web browser to *.* to be able to see the file. The file will be copied to the Switch, and once this has completed, the Switch will restart. Although the upgrade process has been designed to preserve your configuration settings, 3Com recommends that you make a backup of the configuration beforehand, in case the upgrade process fails for any reason (for example, the connection between the computer and the Switch is lost while the new software is being copied to the Switch). A progress screen displays while the upgrade is taking place. The upgrade procedure can take a few minutes, and is complete when the progress bar has finished running and the Power LED has stopped flashing and is permanently green.
