Connecting external devices
If you install a supported optional adapter, you can attach external devices to the server.

Note: If you are attaching an external device, see the documentation that comes with the device for information about cabling.
1.Read and understand the Safety, Warranty, and Support Information at http://www.lenovo.com/support, and “Guidelines” on page 35.
2.Turn off the server and all attached devices.
3.Follow the instructions that come with the device to prepare it for installation and to connect it to the server.
Updating the server configuration
When you start the server for the first time after you install or remove an internal option or external device, you might receive a message saying that the configuration has changed. The Setup Utility program starts automatically so that you can save the new configuration settings.
Some options have device drivers that you must install. For information about installing device drivers, see the documentation that comes with each option.
You can obtain device drivers for operating systems that are not preinstalled at http://www.lenovo.com/support. Installation instructions are provided in readme files with the device driver files.
Installing security features
There are several security options available to help you prevent hardware theft and unauthorized access to your server. In addition to physical locks, you can also prevent unauthorized use of your server by a software lock that locks the keyboard until a correct password is typed in.
Note: Make sure that any security cables you installed do not interfere with other server cables.
Integrated cable lock

Padlock
Your server is equipped with a padlock loop so that the cover cannot be removed when a padlock is installed.
Password protection
To deter unauthorized use of your server, you can use the Setup Utility program to set a password. When you turn on your server, you are prompted to type the password. The server cannot be used until a valid password is typed in. Refer to Chapter 5 “Configuring the server” on page 21 for more information.
