Drive Grounding
Care should be taken when mounting the drive in a system chassis. The drive should be mounted using four screws in the side
mounting holes (positions 
A, B, C,
and
D
as in 
 Figure 4
 and 
 Figure 5
) or bottom mounting holes (positions 
1, 2, 3,
and
4
 as in 
 Figure
 
5
) grounded to the system chassis. At least one mounting screw is required for proper grounding. See 
 Figure 4
 for drive grounding
using four screws in the side mounting holes and 
 Figure 5
 for drive grounding using four screws in the bottom mounting holes. The
sidewall surfaces 
A1
, 
A2, A3
(cross-hatched green shaded areas as in 
 Figure 4
) and the green highlighted area (as labeled in 
 Figure 5
) 
should not be used for system grounding purposes.

The green highlighted area (PCBA as in 
 Figure 5
) should never make contact with the system chassis to prevent electrical shorting of 
the drive. Contact must be limited to side mounting holes (positions 
A, B, C,
and 
D 
as in 
 Figure 4
and 
 Figure 5
) or bottom mounting
holes (positions 
1, 2, 3,
and 
4 
as in 
 Figure 5
).

Notes:
• Side Mounting - Use four metal screws in 
positions 
A, B, C,
and 
D
.
• Bottom Mounting - Use four metal screws in 
positions
