(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.
