1.2 Managing the GPON Device

browser such as Firefox or Internet Explorer. The Web Configurator gives you access to all the available
settings for this product. For details on connecting to it, see the

1.3 Good Habits for Managing the GPON Device

Do the following things regularly to make the GPON Device more secure and to manage the GPON
Device more effectively.
• Change the web configurator login password. Use a password that's not easy to guess and that
consists of different types of characters, such as numbers and letters.
• Write down the password and put it in a safe place.
• 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.
