To install a new optical drive:

NOTE: Make sure the jumper on the new drive is in the CS (Cable Select) position.

1Slide the new optical drive through the front of the computer. Don’t slide the drive in all the way — you need room to attach the cables.

2Connect the cables to the back of the drive(s).

3Push the drive(s) all the way in, align the screw holes and insert the screws as follows:

Upper drive bay, full-sized drive — use C screw holes.

Lower drive bay, full-sized drive — use D screw holes.

Lower drive bay, 3.5-inch drive in an adapter tray — use the rear (D) slotted screw hole and the (G) forward screw hole. This positions the 3.5- inch drive tray flush with the front cover.

NOTE: The 3.5-inch drive option applies only to Chassis I and II, and is not available for Chassis III.

To reassemble the computer:

1Replace the fan duct and side panel (see “closing the computer“ on page 140).

2Skip this step if you are installing a full-sized drive or if you have Chassis III. Prepare the front cover when a 3.5-inch drive is in the lower drive bay: Remove the lower bay door by inserting a screwdriver blade at H (5 places) on the inside of the cover. Pry the door off the front cover.

NOTE: This step applies only to Chassis I and II, and is not available for Chassis III.
