Seagate ST3500071FC, ST3400071FC manual Vibration, Air cleanliness

6.4.4.2Vibration

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 0.5 G RMS (grams root mean square)

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 1.2 G RMS (grams root mean square)

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 1.2 G RMS (grams root mean square)

6.4.5Air cleanliness

The drive is designed to operate in a typical office environment with minimal environmental control.
