(1) Mounting frame structure
Special attention must be given to mount the IDD disk enclosure (DE) as follows.
a) Use the frame with an embossed structure, or the like. Mount the IDD with making a gap
of 2.5 mm or more between the IDD and the frame of the system.
b) As shown in Figure 4.4, the inward projection of the screw from the IDD frame wall at the
corner must be 5.0 mm or less.
c) Tightening torque of screw must be secured with 0.59N·m (6kgf·cm) ±12%.
