6.8.3 Operating shock

The drive meets IBM Standard C-S 1-9711-007 for the S5 product classification. The drive meets the
following criteria while operating in the conditions described below. The shock test consists of 10 shock
inputs in each axis and direction for total of 60. There must be a delay between shock pulses long
enough to allow the drive to complete all necessary error recovery procedures.
No error occurs with a 10 G half-sine shock pulse of 11 ms duration in all models.
No data loss occurs with a 30 G half-sine shock pulse of 4 ms duration in all models.
No data loss occurs with a 55 G half-sine shock pulse of 2 ms duration.

6.8.4 Nonoperating shock

The drive will operate with no degradation of performance after being subjected to shock pulses with the
following characteristics.
6.8.4.1 Trapezoidal shock wave
Approximate square (trapezoidal) pulse shape
Approximate rise and fall time of pulse is1 ms
Average acceleration level is 50 G. (Average response curve value during the time following the 1 ms
rise time and before the 1 ms fall with a time "duration of 11 ms")
Minimum velocity change is 4.23 meters per second
6.8.4.2 Sinusoidal shock wave
The shape is approximately half-sine pulse. The figure below shows the maximum acceleration level and
duration.
