Air Cleanliness - Seagate ST3400071FC Product Manual

6.4.4.2 Vibration
a. Operating - normal
The drive as installed for normal operation, shall comply with the complete specified performance while
subjected to continuous vibration not exceeding
5-22 Hz @ 0.25 G (zero to peak)
22-350 Hz @ 0.50 G (zero to peak)
350-500 Hz @ 0.25 G (zero to peak)
Vibration may be applied in the X, Y, or Z axis.
Operating normal translational random flat profile
10 - 500 Hz
b. Operating - abnormal
Equipment as installed for normal operation shall not incur physical damage while subjected to periodic
vibration not exceeding:
15 minutes of duration at major resonant frequency
0-22 Hz @ 0.25 G (X, Y, or Z axis, zero to peak)
22-350 Hz @ 0.50 G (X, Y, or Z axis, zero to peak)
350-500 Hz @ 0.25 G (X, Y, or Z axis, zero to peak)
Vibration occurring at these levels may degrade operational performance during the abnormal vibration
period. Specified operational performance will continue when normal operating vibration levels are
resumed. This assumes system recovery routines are available.
Operating abnormal translational random flat profile
10 - 500 Hz
c. Non-operating
The limits of non-operating vibration shall apply to all conditions of handling and transportation. This
includes both isolated drives and integrated drives.
The drive shall not incur physical damage or degraded performance as a result of continuous vibration not
exceeding
5-22 Hz @ 0.25 G (zero to peak)
22-350 Hz @ 5.00 G (zero to peak)
350-500 Hz @ 1.0 G (zero to peak)
Vibration may be applied in the X, Y, or Z axis.
Non-operating translational random flat profile
10 - 500 Hz
