Environmental temperature
Temperature condition at installed in a cabinet is indicated with ambient temperature measured 3
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 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.
