Barracuda ES.2 FC Product Manual, Rev. B
29
Drives packaged in single or multipacks with a gross weight of 20 pounds (8.95 kg) or less by Seagate for
general freight shipment shall withstand a drop test from 48 inches (1,070 mm) against a concrete floor or
equivalent.
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 Gs, Limited displacement
22 - 350 Hz
0.5 Gs
350 - 500 Hz
0.25 Gs
Vibration may be applied in the X, Y, or Z axis.
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
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
5 - 500 Hz
0.75 Gs (0 to peak)
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
2 Gs (0 to peak, linear, swept sine, 0.5 octave/min)
22 - 350 Hz
5 Gs (0 to peak, linear, swept sine, 0.5 octave/min)
350 - 500 Hz
2 Gs (0 to peak, linear, swept sine, 0.5 octave/min)
Vibration may be applied in the X, Y, or Z axis.
6.4.5
Acoustics
Sound power during idle mode shall be 2.9 bels typical when measured to ISO 7779 specification. Sound
power while operating shall be 3.2 bels typical when measured to ISO 7779 specification.
There will not be any discrete tones more than 10 dB above the masking noise on typical drives when mea-
sured according to Seagate specification 30553-001. There will not be any tones more than 24 dB above the
masking noise on any drive.
6.4.6
Air cleanliness
The drive is designed to operate in a typical office environment with minimal environmental control.
6.4.7
Corrosive environment
Seagate electronic drive components pass accelerated corrosion testing equivalent to 10 years exposure to
light industrial environments containing sulfurous gases, chlorine and nitric oxide, classes G and H per ASTM
B845. However, this accelerated testing cannot duplicate every potential application environment.
