Mounting orientation

1. Mount the HDD with M2.5 screws. Take care not to add any excessive "distorting" force to the HDD when mounting. Using 4 screws holes, secure the HDD.
2. Use screws with the following specifications when the HDD is mounted:
   1. M2.5 (screw engagement of 2.8mm max. However, do not use both bottom and side screw hole at the same position simultaneously.)
   2. The torque for fixing the screws is 2.5±0.5kgcm(2.2±0.4 lb. inch)
3. Any distortion of HDD over 0.015mm should be avoided. Take care that the system chassis are flat enough.
4. Consider an appropriate cooling to keep the temperature of center of HDD top cover less than 65°C.
5. The inertia of the chassis around the Z-axis of the gravity center of the device must be more than 3 X 10-4 kg m2.
