CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.

CAUTION: For configurations with three SAS hard drives, you must install an additional fan (see "Installing an Additional Fan" on page 210).

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.

NOTICE: To avoid damage to the hard drive, do not place the drive on a hard surface. Instead, place the drive on a sufficiently cushioned surface, such as a foam pad.

NOTICE: Mixing SATA and SAS hard drives in the same RAID configuration may cause your computer to not function properly.
