Clear Button
This button is used for:
¦ Deleting Passwords - When pressed by itself for at least one 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 as a convenience, however if you
are concerned with the security of the switch configuration and operation,
you should make sure the switch is installed in a secure location. This
button can be disabled by a CLI command.
