8.2.1J6 connector requirements

Recommended mating connector part number: Berg receptacle, 6-position, Berg part number 690-006.

8.3Drive orientation

The drive may be mounted in any orientation. All drive performance characterizations, however, have been done with the drive in horizontal (discs level) and vertical (drive on its side) orientations, which are the two pre- ferred mounting orientations.

8.4Cooling

The host enclosure must dissipate heat from the drive. You should confirm that the host enclosure is designed to ensure that the drive operates within the temperature measurement guidelines described in Section 6.4.1. In some cases, forced airflow may be required to keep temperatures at or below the temperatures specified in Section 6.4.1.

If forced air is necessary, possible air-flow patterns are shown in Figure 16. 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.

Note. Air flows in the direction shown (back to front) or in reverse direction (front to back)
