a Push the release lever to release the top tab.

tab releases automatically).

7 Pull the two front-panel tabs towards you, and then push out the front-panel insert.
8 Ensure that the jumper setting on the new drive is set for "cable select" (see the
documentation that came with the drive for information).
9 Remove two extra alignment screws, shown in the illustration on page 62, from the front of
the computer and insert them into the drive.

need two alignment screws for this procedure.
10 Gently slide the drive into place.
11 Once the drive is in place, apply pressure to ensure that the drive is fully seated.
12 Use the securing screw that came with the drive to attach the drive to the computer.
CAUTION: Match the colored strip on the cable with pin 1 on the drive (pin 1 is marked as "1").

middle data connector to the new drive.

fan and cooling vents.
16 Reattach the front panel to the side hinges, and then rotate it until it snaps onto the front of
