Temperature:
°
Up to 72-hour storage: - 40° to 150° F (-40° to 66° C)
°
Up to 6-month storage: -20° to 131° F (-29° to 55° C)

Reasonable rate of change with noncondensing relative humidity during the
transition from warm to cold
•
Relative humidity: 10% to 80%, noncondensing
•
Altitude: 0 to 40,000 feet (0 to 12,192 meters)
Cooling Airflow Direction
Each enclosure includes its own forced-air cooling fans or blowers. Air flow for each
enclosure enters from the front of the modular cabinet and rack and exhausts at the
rear.

Calculating Specifications for Enclosure
Combinations
The example configuration in this subsection shows listed components installed in a
single modular (42U) HP modular cabinet. Cabinet weight includes the PDUs and their
associated wiring and receptacles.
Power and thermal calculations assume that each enclosure in the cabinet is fully
populated; for example, a NonStop Blade Element with four processors. The power
and heat load is less when enclosures are not fully populated, such as a NonStop
Blade Element with fewer processors or less memory, a Fibre Channel disk module
with fewer disk drives, or an LSU enclosure with fewer LSUs.
AC current calculations assume that one PDU delivers all power. In normal operation,
the power is split equally between the two PDUs in the cabinet. However, calculate the
power load to assume delivery from only one PDU to allow the system to continue to
operate if one of the two AC power sources or PDUs fails.
This example show completed weight, power, and thermal calculations for each
cabinet in the system. For a total thermal load for a system with multiple cabinets, add
the heat outputs for all the cabinets in the system.
