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 5 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.
• 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.
Notes:
1. Dimensions are shown in inches (mm).
2 Dimensions per SFF-8301 specification.
