Dell Dimension U7021 Owner's Manual page 100

3 If you are installing a replacement drive and the new drive does not have the bracket rails
attached, remove the rails from the old drive by removing the two screws that secure each rail
to the drive. Attach the bracket to the new drive by aligning the screw holes on the drive with
the screw holes on the bracket rails and then inserting and tightening all four screws (two
screws on each rail).
4 Gently slide the drive into place until the tabs securely click into position.
5 Connect the power and data cables to the drive.
If you are adding a drive that has an audio cable, connect the audio cable to the audio
connector on the system board.
