Upgrade
Upgrade Screen
The Upgrade facility allows you to install on the Router 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,
select
Browse
to tell your web browser where this file is on your
computer, and then click
Apply
. The file will be copied to the Router, and
once this has completed, the Router 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 Router is lost while the new
software is being copied to the Router).

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 Router during the upgrade
procedure; if you do, the software may be corrupted and the Router may
not start up properly afterwards. .
