General Installation Guidelines

Connecting Drive Cables
When you install a drive, you connect two cables—a DC power cable and a data cable—to the back of the drive.
Drive Interface Connectors
NOTE: Due to the limited number of drive bays and controllers on this computer, you will not be able to connect all supported devices at once.
NOTE: If you will be operating your computer without an optical drive or a 3.5-inch device (floppy drive or media card reader) installed, the appropriate
drive-bay insert must be installed in place of the drive. Contact Dell if you need a drive-bay insert.
