If forced air is determined to be necessary, possible air-flow patterns are shown in Figure 9. The air-flow patterns are created 
by one or more fans, either forcing or drawing air as shown in the illustrations. Conduction, convection, or other forced air-
flow patterns are acceptable as long as the temperature measurement guidelines of Section 6.5.1 are met.

Mount the drive using the bottom or side mounting holes. If mounting the drive using the bottom holes, ensure to not 
physically distort the drive by attempting to mount it on a stiff, non-flat surface.

The allowable mounting surface stiffness is 80 lb/in (14.0 N/mm). The following equation and paragraph define the allowable 
mounting surface stiffness: 

where K is the mounting surface stiffness (units in lb/in or N/mm) and X is the out-of-plane surface distortion (units in inches 
or millimeters). The out-of-plane distortion (X) is determined by defining a plane with three of the four mounting points fixed 
and evaluating the out-of-plane deflection of the fourth mounting point when a known force (F) is applied to the fourth point.

Signal ground (PCBA) and HDA ground are connected together in the drive and cannot be separated by the user. The 
equipment in which the drive is mounted is connected directly to the HDA and PCBA with no electrically isolating shock 
mounts. If it is desired for the system chassis to not be connected to the HDA/PCBA ground, the systems integrator or user 
must provide a nonconductive (electrically isolating) method of mounting the drive in the host equipment.

Increased radiated emissions may result if maximum surface area ground connection is not provided between system 
ground and drive ground. This is the system designer’s and integrator’s responsibility.
