Chapter 1 Getting to Know Your X6004
• Write down the administrator 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 X6004 to its factory
default settings. If you backed up an earlier configuration file, you would not have to
totally re-configure the X6004. You could simply restore your last configuration.
