Barracuda 5400.1 Product Manual, Rev. G 15

2.10.5Shock

All shock specifications assume that the drive is mounted securely with the input shock applied at the drive mounting screws. Shock may be applied in the X, Y or Z axis.

2.10.5.1Operating shock

These drives comply with the performance levels specified in this document when subjected to a maximum operating shock of 63 Gs based on half-sine shock pulses of 2 msec. Shocks should not be repeated more than two times per second.

2.10.5.2Nonoperating shock

The nonoperating shock level that the drive can experience without incurring physical damage or degradation in performance when subsequently put into operation is 350 Gs based on a nonrepetitive half-sine shock pulse of 2 msec duration.

2.10.6Vibration

All vibration specifications assume that the drive is mounted securely with the input vibration applied at the drive mounting screws. Vibration may be applied in the X, Y or Z axis.

2.10.6.1Operating vibration

The following table lists the maximum vibration levels that the drive may experience while meeting the performance standards specified in this docu- ment.

5–21 Hz	0.02-inch displacement (peak to peak)
22–350 Hz	0.50 Gs acceleration (zero to peak)

2.10.6.2Nonoperating vibration

The following table lists the maximum nonoperating vibration that the drive may experience without incurring physical damage or degradation in perfor- mance when subsequently put into operation.

5–21 Hz	0.2-inch displacement (peak to peak)
22–350 Hz	5.0 Gs acceleration (zero to peak)
