1.9.5 Shock and vibration
Mount the drive for normal operation as recommended in Section 2.4 on
page 23. Shock and vibration may be applied in the X, Y or Z axis.
Episodes are not repeated more than twice per second.
The shock and vibration limits specified in this document are measured
directly on the chassis. If the drive is installed in an enclosure to which
the shock or vibration is applied, the resonances within the enclosure
may not subject the drive to movement that exceeds the specification
limits. The enclosure must be modified to ensure that the drive movement
complies with the specification.
