Chapter 1 Getting to Know Your NBG420N 1.5 Ways to Manage the NBG420N Use any of the following methods to manage the NBG420N. • Web Configurator. This is recommended for everyday management of the NBG420N using a (supported) web browser. • Command Line Interface. Line commands are mostly used for troubleshooting by service engineers. • FTP. Use File Transfer Protocol for firmware upgrades and configuration backup/restore. 1.6 Good Habits for Managing the NBG420N Do the following things regularly to make the NBG420N more secure and to manage the NBG420N 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 NBG420N to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the NBG420N. You could simply restore your last configuration. 1.7 LEDs Figure 3 Front Panel The following table describes the LEDs.
