Figure 47 Upgrade Screen
The Upgrade facility allows you to install on the Gateway any new releases of
system software that 3Com may make available. To install new software, you first
need to download the software from the 3Com support web site to a folder on
your computer. Once you have done this, use the Browse button to tell your web
browser where this file is on your computer, and then click on Apply. The file will
be copied to the Gateway, and once this has completed, the Gateway will restart.
Although the upgrade process has been designed to preserve your configuration
settings, it is recommended 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 Gateway is lost while the new
software is being copied to the Gateway).
The upgrade procedure can take up to two minutes, and is complete when the
Alert LED has stopped flashing and is permanently off. Make sure that you do not
interrupt power to the Gateway during the upgrade procedure; if you do, the
software may be corrupted and the Gateway may not start up properly
afterwards. If the Alert LED comes on continuously after a failed upgrade, refer to
Chapter 6, Troubleshooting.
