Holes for

Mounting screw

In case of using a center hole,

use it in combination with the

holes of both ends.

Holes for mounting screw

Use four holes (No.1 to No.4) to mount.

Figure 4.5 Limitation of side-mounting

(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 the surface temperature of specific ICs and the DE. These measurement results

must satisfy the temperature condition listed in Table 4.1.
