colored pull-tab and pull until the connector detaches.

Installing a Hard Drive
1. If you are installing a new drive, rather than replacing a drive, attach the drive rails—located inside the cover—to the new drive and proceed with
step 8 .
2. If you are replacing a hard drive that contains data you want to keep, back up your files before you begin this procedure.
3. Check the documentation for the drive to verify that the drive is configured for your computer.
4. Follow the procedures in Before You Begin .
5. Grasp the drive rails, push the two rails toward each other, slide the drive slightly forward, and rotate the hard drive up and away from the bracket.
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.
CAUTION: To guard against electrical shock, always unplug your computer from the power supply before removing the hard drive.
NOTICE: To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of your
computer's electronic components. You can do so by touching an unpainted metal surface on the computer chassis.
NOTICE: To avoid damage to the drive, do not set it on a hard surface. Instead, set the drive on a surface, such as a foam pad, that will sufficiently
cushion it.
