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

5-22Hz @ 0.045 inches (1.143 mm) displacement (peak to peak) 22-300 Hz @ 1.1 G (zero to peak)

300-350 Hz @ 0.83 G (zero to peak)

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:

5-22 Hz @ 0.061 inches (1.5494 mm) displacement (peak to peak) 22-300 Hz @ 1.5 G (zero to peak)

300-350 Hz @ 1.125 G (zero to peak)

Vibration may be applied in the X, Y, or Z axis.

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.

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 @ 0.10 inches (2.54 mm) displacement (peak to peak) 22-400 Hz @ 2.5 G (zero to peak)

Vibration may be applied in the X, Y, or Z axis.

6.4.5Air cleanliness

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

6.4.6Acoustics

Sound power during idle mode shall be 3.8 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.

6.4.7Electromagnetic susceptibility

See Section 2.1.2.
