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)
