Mounting the drive and connecting cables

Do not touch the connector pins or any components on the control board without observing static-discharge precautions. Always handle the drive by the frame only.

The drive may be mounted in any orientation (horizon- tally, vertically, and any combination thereof); however, you must ensure that the drive receives adequate air flow for cooling.

1.Mount the drive to the host system’s chassis using four 6-32 UNC screws. Two mounting holes are in each side of the drive and there are four mounting holes in the bottom of the drive. See Figure 15.

The maximum length that the screws should ex- tend into the chassis mounting holes is 0.15 inch (3.81 mm), measured from the outer surface of the chassis. Tighten the screws down evenly. Do not over-tighten or force the screw if it does not seem to screw in easily, because this means the threads are not properly aligned. In this case, back the screw out and try again.
