Quantum Atlas 10K II Ultra 160/m SCSI Hard Disk Drives 3 − 23
3.6.3 Shock Clip
The shock clip provides an extra level of isolation from the occurrence of a short
duration, non-operational shock, particularly when the disk drive is mounted on a
rigid platform.
CAUTION
To prevent the possibility of a cross-threaded screw, it is recommended that
the screws associated with the fixed side mounting locations be started before
the screw associated with the shock clip. Install all of the applicable screws
before the final torquing process.
Shock performance is optimal when either four bottom mount locations or
four outer side screw locations are used.
3.6.4 Mounting
For the best results during performance benchmark testing, it is recommended that
the disk drive be mounted firmly within a system or a fixture, rather than sitting
unconstrained on a tabletop or work surface. If it is necessary to perform testing on
an unconstrained disk drive, place the disk drive on a flat, smooth, semi-cushioned
surface (similar to a mousepad). This avoids any performance degradations due to
possibly higher incidence of recovered errors. The disk drive should not be operated
on a hard surface.
3.6.5 Ventilation
The Quantum Atlas 10K II Ultra 160/m SCSI hard disk drive operates without a
cooling fan, provided the ambient air temperature does not exceed 131ºF (55ºC).
Figures 3-12 and 3-13 show possible configurations for airflow required for adequate
cooling. Clearance from the drive to any other surface above and below the disk drive
must be a minimum of 1/16-inch (1.25 mm).
