Environment

The following environmental specifications were type-tested under controlled

conditions. Hewlett-Packard maintains an active program of auditing production

products to make sure these specifications remain true when products are retested

under the same conditions. However, the limits of these specifications do not

represent the optimum for long, trouble-free operation and specifically are not

recommended for maximum satisfaction. The recommended conditions are

stated when appropriate.

■ Operating temperature: 5º C to 40º C (50º F to 104º F)

Recommended: 20º C to 25.5º C (68º F to 78º F)

■ Maximum gradient: 20º C per hour (36º F per hour)

■ Relative humidity: 20% to 80% noncondensing, max. wetbulb at 26º C

Recommended: 30% to 50% noncondensing

■ Altitude: 3000 m (10,000 ft.)

Note For continuous, trouble-free operation, the disk system should

NOT be operated at its maximum environmental limits for

extended periods of time. Operating within the recommended

operating range, a less stressful operating environment, ensures

maximum reliability.

The environmental limits in a nonoperating state (shipping and storage) are

wider:

■ Temperature: -40º C to 70º C (-40º F to 158º F)

■ Maximum gradient: 24º C per hour (43.2º F per hour)

■ Relative humidity: 15% to 90% noncondensing

■ Altitude: 4600 m (15,000 ft.)

Acoustics

■ Sound power: 7.3 Bels

■ Sound pressure at operator’s position: 56.3 dB(A)
