Micropolis 1664-Models


1664 Drive DIMENSIONS AND MOUNTING INFORMATION The Micropolis 1664 drive uses industry-standard mounting for 5 1/4-inch "half-height" Winchester disk drives. Recommended orientation is vertical on either side, or horizontal with the Device Electronics board down; other mounting orientations may be used provided the ambient air temperature around the drive is kept at or below 50° C (122° F). Inasmuch as the drive acts as a heat sink to dissipate heat from the unit, the enclosure and mounting structure should be designed to allow natural convection of heat around the HDA and frame. If the enclosure is small or natural convection is limited, a fan may be required. In any case, no point on the HDA assembly should exceed 62° C (143° F). The figure below shows the mounting hole locations.


To avoid restricting HDA sway space, the mounting screws must not penetrate the side mounting holes by more than 0.10 (+.00, -.03) inch, or the bottom mounting holes by more than 0.20 (+.00, -.03) inch. Torque applied to screws must not exceed 8 in-lbs.
