Installation Conditions

(4) Ambient temperature

The temperature conditions for a disk drive mounted in a cabinet refer to the ambient temperature at a point 3 cm from the disk drive. The ambient temperature must satisfy the temperature conditions described in Section 1.4, and the airflow must be considered to prevent the DE surface cover temperature from exceeding 60 °C.

Provide air circulation in the cabinet such that the PCA side, in particular, receives sufficient cooling. To check the cooling efficiency, measure the surface cover temperatures of the DE. Regardless of the ambient temperature, this surface cover temperature must meet the standards listed in Table 3.1. Figure 3.4 shows the temperature measurement point.
