(3)Limitation of bottom-mounting

Use all 4 mounting holes on the bottom face.

(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.
