HP 3000 Enterprise Virtual Array - Manual (Page 127)

Table 32 Environmental operating specifications
Ambient temperature : +10 °C to +35 °C (+50 °F to +95 °F) with an
average rate of change of 1 °C/hour maximum and a step change of 3 °C
or less. Maintaining the optimum ambient temperature within the specified
range ensures that the internal operating temperatures support the drive
manufacturer’s MTBF specifications.
Relative humidity: 40% to 60% (noncondensing) with a step change of 10%
or less (noncondensing)
Air quality: Not to exceed a maximum of 500,000 particles, 0.5 micron or
larger, per cubic foot of air.
Heat dissipation: 1600 BTUs per hour
When shipping, or placing this product in short term storage, HP recommends maintaining the
environmental conditions listed in Table 33 .
Table 33 Environmental shipping or short-term storage specifications
Ambient temperature : –40 °C to +66 °C (–40 °F to +151 °F)
Relative humidity: 10% to 80% noncondensing
Altitude: below 15,240 m (50,000 ft)
Power specifications
The input voltage to the drive enclosure power supplies is a function of the country-specific input voltage
to Enterprise storage system rack power distribution units (PDUs). Table 34 defines the AC input power
available to the drive enclosure power supplies.
CAUTION:
The AC power distribution within a rack ensures a balanced to each PDA and reduces the possibility of
an overload condition. Changing the cabling to or from a PDM could cause an overload condition.
