We test vibration two ways:

Operating: While operating, the product vibrates for a minimum of one

hour each at the X,Y, and Z axes at a rate of 15 minutes per sweep cycle over

a frequency range of 5 to 2000Hz.

Non-operating: With no power applied, the product vibrates for a minimum

of one hour each at the X,Y, and Z axes at a rate of 15 minutes per sweep

cycle over a frequency range of 5 to 2000Hz.

Dust

The Winchester disk drive of your mass storage system contains its own air

filtration system. The system permits circulation of internal air and equalization
