Table 29 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 30 .
Table 30 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: 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). Enterprise storage system AC input line
voltages 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.
