Weight
Cooling airflow through each enclosure in the Integrity NonStop NS1000 server is
front-to-back. Because of high heat densities and hot spots, an accurate assessment
of air flow around and through the server equipment and specialized cooling design is
essential for reliable server operation. For an airflow assessment, consult with your HP
cooling consultant or your heating, ventilation, and air conditioning (HVAC) engineer.
Because each modular cabinet houses a unique combination of enclosures, use the
Heat Dissipation Specifications and Worksheet on page 3-11 to calculate the total heat
dissipation for the hardware installed in each cabinet. For air temperature levels at the
site, refer to Operating Temperature, Humidity, and Altitude on page 3-11.
Weight
Because modular cabinets for Integrity NonStop NS1000 servers house a unique
combination of enclosures, total weight must be calculated based on what is in the
specific cabinet, as described in Modular Cabinet and Enclosure Weights With
Worksheet on page 3-10.
Flooring
Integrity NonStop NS1000 servers can be installed either on the site’s floor with the
cables entering from above the equipment or on raised flooring with power and I/O
cables entering from underneath. Because cooling airflow through each enclosure in
the modular cabinets is front-to-back, raised flooring is not required for system cooling.
The site floor structure and any raised flooring (if used) must be able to support the
total weight of the installed computer system as well as the weight of the individual
modular cabinets and their enclosures as they are moved into position. To determine
the total weight of each modular cabinet with its installed enclosures, refer to Modular
Cabinet and Enclosure Weights With Worksheet on page 3-10.
For your site’s floor system, consult with your HP site preparation specialist or an
appropriate floor system engineer. If raised flooring is to be used, the design of the
Integrity NonStop NS1000 server modular cabinet is optimized for placement on
24-inch floor panels.
Dust and Pollution Control
Integrity NonStop NS1000 servers do not have air filters. Any computer equipment can
be adversely affected by dust and microscopic particles in the site environment.
Airborne dust can blanket electronic components on printed circuit boards, inhibiting
cooling airflow and causing premature failure from excess heat, humidity, or both.
Note. Failure of site cooling with the server continuing to run can cause rapid heat buildup and
excessive temperatures within the hardware. Excessive internal temperatures can result in full
or partial system shutdown. Ensure that the site’s cooling system remains fully operational
when the server is running.
