Replacing the cover and connecting the cables

After working with options, you need to install any removed parts, close the computer cover, and reconnect cables, including telephone lines and power cords. Also, depending on the option that is installed, you might need to confirm the updated information in the Setup Utility program.

To replace the computer cover and connect cables to your computer:

1.Ensure that all components have been reassembled correctly and that no tools or loose screws are left inside your computer.

2.Reposition any cables that might impede the replacement of the computer cover.

3.Align the drive bay assembly with the two slots and rails on the sides of the chassis, reconnect the drive cables on the system board, and then slide the drive bay assembly towards the rear of the chassis until it snaps into position.

4.Reinstall the two screws that secure the drive bay assembly.

5.Reinstall the front bezel if it was removed.

6.Position the computer cover on the chassis so that the rail guides on the sides of the cover engage the rails and push the cover to the closed position. Install the two screws that secure the computer cover.

7.Install any locking devices such as a padlock as necessary.

8.If your computer is being placed in the vertical position, attach the floor stand.

9.Reconnect the external cables and power cords to the computer. See “Locating connectors on the rear of your computer” on page 8.

10.To update the configuration, see Chapter 2, “Using the Setup Utility,” on page 23.
