Server locks
Locking the server cover prevents unauthorized access to the inside of your server. Locking the front door 
(available on some models) prevents unauthorized access to the installed drives.
Padlock
Your server comes with a padlock loop. When a padlock is installed, the server cover cannot be removed.

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:
