• Back up the configuration (and make sure you know how to restore it). Restoring an earlier
working configuration may be useful if the GPON Device becomes unstable or even crashes. If
you forget your password, you will have to reset the GPON Device to its factory default settings.
If you backed up an earlier configuration file, you would not have to totally re-configure the
GPON Device. You could simply restore your last configuration.
