3.3.2 Clear Button The clear button is used for the following purposes: • Deleting Passwords - When pressed by itself for at least 1 second, the button deletes any switch console access passwords that you may have configured. Use this feature if you have misplaced the password and need console access. This button is provided for your convenience, but its presence means that if you are concerned with the security of the switch configuration and operation, make sure the switch is installed in a secure location, such as a locked wiring closet. • Restoring Factory Default Configuration - When pressed with the Reset button in a specific pattern, any configuration changes you may have made through the switch console, the Web browser interface, and SNMP management are removed, and the factory default configuration is restored to the switch.
