22.1 Overview
Use the instructions in this chapter to change the device’s configuration file or
upgrade its firmware. After you configure your device, you can backup the
configuration file to a computer. That way if you later misconfigure the device, you
can upload the backed up configuration file to return to your previous settings.
You can alternately upload the factory default configuration file if you want to
