If you have a hard disk drive installed in the vertical mounting position, remove this drive before you remove or install a disk drive in a horizontal drive bay. See “Removing a Hard Disk From the Vertical Position,” on page B-24.

If you do not need to remove a hard disk drive from the vertical position (or have already done so), follow the steps under “Removing the Subassembly,” below. You must remove the entire subassembly from the computer before you can install or remove a disk drive in a horizontal drive bay.

Removing the Subassembly

You can remove the subassembly by yourself, but it is easier if you have someone help you.

Follow these steps to remove the subassembly from your computer:

1.Turn the computer so that the front panel is facing you.

2.To remove the front panel, lift up slightly on the three clips at the top of the panel and tilt the panel toward you, as shown below.
