146 Reference
AC Power Input
The disk system operates at 100-127 and 200-240 V AC, 50-60 Hz, single phase,
power factor corrected. Maximum current is 4.8 amps over the low voltage range
and 2.0 amps over the high voltage range. Average power consumption with
medium load (14 disks running idle) is 345 watts.
DC Power Output
■
Disk: +5 V and +12 V from power supply
■
BCC: +5 V and +3.3 V from power supply
Heat Output
1600 BTU/hr.
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 38º C (41º F to 100º F)
Recommended: 20º C to 25.5º C (68º F to 78º F)
■
Storage temperature: -40º C to 70º C (-40º F to 158º F)
■
Maximum gradient: 20º C per hour (36º F per hour)
■
Relative humidity:10% to 80% noncondensing, max. wetbulb at 28º 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.
