3Com 2250 Upgrading the System Software

40 CHAPTER 4: CONFIGURING THE SWITCH

■To reload configuration settings that you previ-

ously 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 configu-

ration 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 Configu-

ration” 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 run-

ning and the Power LED has stopped flashing and is

permanently green.
