2.1 Drive mounting

You can mount the drive in any orientation using four screws in the side- mounting holes or four screws in the bottom-mounting holes. See Figure 3 for drive mounting dimensions. Follow these important mounting precautions when mounting the drive:

•Allow a minimum clearance of 0.030 inches (0.76 mm) around the entire perimeter of the drive for cooling.

•Use only 6-32 UNC mounting screws. Insert the screws no more than

0.20inch (5.08 mm) into the bottom mounting holes and no more than

0.14inch (3.55 mm) into the side mounting holes.

•Do not overtighten the mounting screws (maximum torque: 6 inch-lb).

•Do not use a drive interface cable that is more than 18 inches long.

Note: Dimensions are shown in inches (mm).
