If forced air is necessary, possible air-flow patterns are shown in Figure 13. The air-flow patterns are created
by 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 6.4.1 are met.

8.3 Drive mounting
Use M3 x .5 metric screws to mount the drive using the side, bottom, or end mounting holes. Select a screw
length that results in a minimum thread engagement of 0.12 inches when using the side-mounting holes or a
minimum thread engagement of 0.10 inches when using the bottom or end mounting holes. Use a maximum
torque of 4.5 +/- .45 in lbs. If the screws are torqued above the specified values, threads could be stripped.
Note. Before mounting the drive in any kind of adapter frame, verify that the drive can meet the shock and
vibration specifications while mounted in the adapter frame.
8.4 Grounding
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 electri-
cally 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 mount-
ing the drive in the host equipment.
Increased radiated emissions may result if you do not provide the maximum surface area ground connection
between system ground and drive ground. This is the system designer’s and integrator’s responsibility.
