cm 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 55°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.
