3Com 2226 PLUS - Manual (Page 36)

36 C HAPTER 4: C ONFIGURING THE S WITCH
2 Once you have downloaded the firmware, use the
Browse button to locate the file on your computer, and
then click OK.
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:
1 Click 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 33). You may need to restart your computer to
re-establish communication with the Switch.
Reboot
Clicking on Administration, then Reboot on the menu
has the same effect as power cycling the unit. No
configuration information will be lost. Reboot the
Switch if you are experiencing problems and you want
to re-establish your Internet connection.
Any network users that are currently accessing the
Internet will have their access interrupted while the
reboot takes place, and they may need to restart their
computers when the reboot has completed and the
Switch is operational again.
