3Click Restore to copy the configuration back to the Switch.

For security purposes, restoring the configuration does not change the password.

Firmware Upgrade

The Upgrade facility allows you to install on the Switch any new releases of system firmware that 3Com may make available.

Newer versions of firmware can be downloaded via HTTP and copied to the Switch; the Switch will restart and apply the newer system firmware version.

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 firmware 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.

CAUTION: Do not interrupt power to the Switch during the upgrade procedure. If you do, the firmware may be corrupted and the Switch may not start up properly afterwards.

Initialize

To reset the Switch to factory default settings:

1Click Administration, then Initialize on the menu.

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
