Kensington-style cable lock
You can use a Kensington-style cable lock to secure your server to a desk, table, or other non-permanent 
fixture. The cable lock attaches to the security-lock slot at the rear of your server and is operated with a key 
or combination depending on the type selected. The cable lock also locks the server cover. This is the same 
type of lock used with many notebook computers. You can order such a cable lock directly from Lenovo by 
searching for Kensington at:
