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 55°C.
An air flow with an adequate wind velocity must be maintained to
deal with much heat generated from the MAC30xxFC.
Reference value: An air flow with a wind velocity of more than 0.5
•
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.

Limitation of side-mounting
CAUTION
m/s is required in an environment at 40°C, and
an air flow with a wind velocity of more than
1.0m/s in an environment at 45°C (Center of DE
cover ≤ 55°C).
