(4) Environmental temperature

Temperature condition at installed in a cabinet is indicated with ambient temperature measured

30 mm from the disk drive. At designing the system cabinet, consider following points.

• Make a suitable air flow so that the DE surface temperature does not exceed 60°C.

• Cool the PCA side especially with air circulation inside the cabinet. Confirm the cooling effect

by measuring temperature of specific ICs and the DE. These measurement results should be

within a criteria listed in Table 4.1.

Table 4.1 Surface temperature check point
