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. For the specific method to restore the factory default
configuration, see the troubleshooting section of HP ProCurve Switch 2800 Series Installation
and Getting Started Guide.
