Caution: Save the configuration, then create a backup of your switch files before you
upgrade the switch. Enterasys Networks recommends that you make a backup of the switch files
before you install the upgrade. If an error occurs during the upgrade, you can restore your switch to
its previous state.
Note: If you have made configuration changes but have not saved the changes, use the save
config command to save the changes, before you back up the switch.
