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.
