Environmental s
pecifications
To ensure o ptimum product operation, you must maintain the op erational environmental specifications
listed in Table
29. The ambient temperature (the enclosure air intake o r room temperature) is especially
critical.

Ambient temper
ature:+10°Cto+35°C(+50°Fto+95°F)withanaveragerateofchangeof1°C/hour
maximum and a step change of 3 °C or less. Maintaining the optimum ambient temperature within the
specified rang
e 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 qualit y: Not to exceed a maximum of 500,000 particles, 0.5 micron or larger, per cubic foot of air.

When shippin
g, or placing this product in short term storage, HP recommends m aintaining the
environmental conditions listed in Table 30.
Table 30 Environmental shippin g or short-term storage specifications
Ambient temperature:–40°Cto+66°C(–40°Fto+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 countr y -specificinputvoltage
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 p ower supplies.
CAUTION:
The AC power distri bution 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.
