Seagate ST4000VM000 manual Shock, Vibration

www.seagate.com Drive Specifications

2.9.5 Shock

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.

2.9.5.1Operating shock

These drives comply with the performance levels specified in this document when subjected to a maximum operating shock of 80 Gs based on half-sine shock pulses of 2ms during read operations. Shocks should not be repeated more than two times per second.

2.9.5.2Nonoperating shock

The nonoperating shock level that the drive can experience without incurring physical damage or degradation in performance when subsequently put into operation is 300 Gs (for 2TB model) and 350 Gs (for 1TB) based on a nonrepetitive half-sine shock pulse of 2ms duration.

2.9.6 Vibration

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, with linear swept sine inputs.

2.9.6.1Operating vibration

The maximum vibration levels that the drive may experience while meeting the performance standards specified in this document are specified below.

2Hz to 22Hz	0.25	Gs (Limited displacement)
22Hz to 350Hz	0.50	Gs
350Hz to 500Hz	0.25	Gs

2.9.6.2Nonoperating vibration

The maximum nonoperating vibration levels that the drive may experience without incurring physical damage or degradation in performance when subsequently put into operation are specified below.

5Hz to 22Hz	3.0	Gs (limited displacement)
22Hz to 350Hz	3.0	Gs
35Hz to 500Hz	3.0	Gs
