Backup configuration allows you to back up (save) the LTE3311’s current configuration to a file on
your computer. Once your LTE3311 is configured and functioning properly, it is highly recommended
that you back up your configuration file before making configuration changes. The backup
configuration file will be useful in case you need to return to your previous settings.
Restore configuration allows you to upload a new or previously saved configuration file from your
computer to your LTE3311.
