1.4 Good Habits for Managing the NBG
Do the following things regularly to make the NBG more secure and to manage the NBG more
effectively.
• Change the 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 device becomes unstable or even crashes. If you
forget your password, you will have to reset the NBG to its factory default settings. If you backed
up an earlier configuration file, you would not have to totally re-configure the NBG. You could
simply restore your last configuration.
