3.5Cooling

Cabinet cooling must be designed by the customer so that the ambient temperature immediately surrounding the drive will not exceed temperature conditions specified in Section 2.9.1, "Ambient temperature."

The rack, cabinet, or drawer environment for the drive must provide heat removal. You should confirm that ade- quate heat removal is provided using the temperature measurement guidelines described in Section 2.9.1.

Forced air flow may be required to keep temperatures at or below the temperatures specified in Section 2.9.1 in which case the drive should be oriented, or air flow directed, so that the least amount of air flow resistance is created while providing air flow to the drive. Also, the shortest possible path between the air inlet and exit should be chosen to minimize the travel length of air heated by the drive and other heat sources within the rack, cabinet, or drawer environment.

If forced air is determined to be necessary, possible air-flow patterns are shown in Figure 4. The air-flow pat- terns are created by one or more 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 guide- lines of Section 2.9.1 are met.

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