Installing a Drive into the 3.5-inch External Drive Bay
The 3.5-inch external drive bay on the front of the computer can be configured with a media card reader
or a diskette drive.
1. Remove/disengage any security devices that prohibit opening the computer.
2. Remove all removable media, such as diskettes or compact discs, from the computer.
3. Turn off the computer properly through the operating system, then turn off any external devices.
4. Disconnect the power cord from the power outlet and disconnect any external devices.
CAUTION: Regardless of the power-on state, voltage is always present on the system board as
long as the system is plugged into an active AC outlet. You must disconnect the power cord to
avoid damage to the internal components of the computer.
5. Remove the access panel and front bezel.
6. If you are installing a diskette drive or media card reader in a bay covered by a bezel blank, remove
the front bezel then remove the bezel blank. See
Removing Bezel Blanks on page 12 for more
information.
7. If you are adding a drive to an empty drive bay for the first time, you must remove the knockout
plate from the bay. To do so, insert a flat screwdriver into the knockout plate slot and rotate the
screwdriver to break the knockout plate out of the chassis. Discard the knockout plate.
8. If the new drive has screws installed on the sides of the drive, remove them before inserting the
drive into the chassis.
9. Slide the drive in through the front of the chassis (1) until the screw holes on the drive are aligned
with the screw holes on the drive cage and install the two M3 metric retainer screws (2) as shown
in the illustration below.
NOTE: Extra drive retainer screws are provided on the interior of the front bezel if needed. The
M3 metric retainer screws for diskette drives or media card readers are black. Refer to
Installing
Additional Drives on page 24 for an illustration of the retainer screws location.
