Vibration
a. Operating in a normal environment
The drive as installed for normal operation operates error free while
subjected to continuous vibration not exceeding:
5-400 Hz @ 0.5 G
Vibration may be applied in the X, Y, or Z axis.
b. Operating in an abnormal environment
Equipment as installed for normal operation does not incur physical
damage while subjected to periodic vibration not exceeding:
15 minutes of duration at major resonant frequency
5-400 Hz @ 0.75 G
Vibration occurring at these levels may degrade operating performance
during the abnormal vibration period. Specified operating performance
continues when normal operating vibration levels are resumed—this
assumes system recovery routines are available.
Abnormal vibration may be applied in the X, Y or Z axis.
c. Non-operating
The limits of non-operating vibration apply to all conditions of handling
and transportation. This includes both isolated drives and integrated
drives.
The drive does not incur physical damage or degraded performance as
a result of continuous vibration not exceeding:
5-22 Hz @ 0.040 inches (1.02 mm) displacement
22-400 Hz @ 2.00 Gs
Vibration may be applied in the X, Y, or Z axis.

Air cleanliness

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

Acoustics

Sound power during idle mode (when the drive is not seeking, reading, or
writing) is 4.7 bels typical when measured to ISO 7779 specifications.

Electromagnetic compatibility

As a component assembly, the drive is not required to meet any
susceptibility performance requirements. The system integrator is
responsible for performing tests to ensure that equipment operating in
the same system as the drive does not adversely affect the perfor-
mance of the drive. See Section 7.2 "DC power requirements."
