Environmental s
pecifications
To ensure optimum product operation, you must maintain the operational environmental specifications
listed in Table
44. The ambient temperature (the enclosure air intake or 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. Maintain ing 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 quality: Not to exceed a maximum of 500,000 particles, 0.5 micron or larger, per cubic foot of air.

tion:12,708BTUsperhour.
When shippin
g, or placing this product in short-term storage, HP recommends maintaining the
environmental conditions listed in Table 45.
