NonStop NS16000 Series Planning Guide (H06.11+)

Nonoperating Temperature, Humidity, and Altitude
• Temperature:
Up to 72-hour storage: -40° to 151° 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 exhausts at the rear.
Typical Acoustic Noise Emissions
70 dB(A) (sound pressure level at operator position)
Tested Electrostatic Immunity
• Contact discharge: 8 KV
• Air discharge: 20 KV
Calculating Specifications for Enclosure Combinations
Figure 14 (page 63) shows components installed in 42U modular cabinets. 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.
NOTE: If your system includes the optional rackmounted HP R5000 UPS, the modular cabinet
will have one PDU located on the rear left side and four extension bars on the rear right side. To
provide redundancy, components are plugged into the left-side PDU and the extension bars. Each
extension bar is plugged into the UPS.
Figure 14 has 16 logical processors with two IOAM enclosures, and 14 Fibre Channel disk modules
installed in three 42U modular cabinets. The weight, power, and thermal calculations for the
components in each cabinet are shown in Table 2 (page 63), Table 3 (page 64), and Table 4
(page 64). For a total thermal load for a system with multiple cabinets, add the heat outputs for
all the cabinets in the system.
