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