Chapter 1 Getting to Know Your Switch • 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 Switch to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the Switch. You could simply restore your last configuration. GS1910/XGS1910 Series User's Guide 9
