Electrical Power and Grounding Quality
Proper design and installation of a power distribution system for a system requires specialized skills,
knowledge, and understanding of appropriate electrical codes and the limitations of the power systems for
computer and data processing equipment. For power and grounding specifications, see Enclosure AC
Input for NonStop X Systems on page 50.
Power Quality
This equipment is designed to operate reliably over a wide range of voltages and frequencies, described
in Enclosure AC Input for NonStop X Systems on page 50
ranges are exceeded. Severe electrical disturbances can exceed the design specifications of the
equipment. Common sources of such disturbances are:
•Fluctuations occurring within the facility’s distribution system
•Utility service low-voltage conditions (such as sags or brownouts)
•Wide and rapid variations in input voltage levels or input power frequency
•Electrical storms or large inductive sources (such as motors and welders)
•Faults in the distribution system wiring (such as loose connections)
To protect the system from electrical disturbances, use a dedicated power distribution system, power
conditioning equipment, and lightning arresters on power cables. For assistance, consult with your
Hewlett Packard Enterprise site preparation specialist or power engineer.

Grounding Systems
The site building must provide a power distribution safety ground/protective earth for each AC service
entrance to all system equipment. This safety grounding system must comply with local codes and any
other applicable regulations for the installation locale.
For proper grounding/protective earth connection, consult with your Hewlett Packard Enterprise site
preparation specialist or power engineer
.
Power Consumption
The power consumption and inrush currents per connection can vary because of the unique combination
of enclosures housed in the rack. Calculate the total power consumption for the hardware installed in the
rack as described in NS7 Enclosure Power Loads
Cooling and Humidity Control
Cooling airflow through each enclosure in the system is front-to-back. Because of high heat densities and
hot spots, an accurate assessment of air flow around and through the system equipment and specialized
cooling design is essential for reliable system operation. For an airflow assessment, consult with your
Hewlett Packard Enterprise cooling consultant or your heating, ventilation, and air conditioning (HV
engineer.
NOTE: Failure of site cooling with the system 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’
running.

Enclosure Weights With Worksheet.
Flooring
NS7 Rack and
NonStop NS7 systems can be installed either on the site’
equipment or on raised flooring with power and I/O cables entering from underneath. Because cooling
airflow through each enclosure in the racks 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 weight of the installed
system, individual racks, and enclosures as they are moved into position. To determine the total weight of
the installation, see
For your site’
appropriate floor system engineer. If raised flooring is to be used, the rack is optimized for placement on
24‑inch floor panels.
s floor system, consult with your Hewlett Packard Enterprise site preparation specialist or an
NS7 Rack and Enclosure Weights With Worksheet on page 58.
Dust and Pollution Control
NS7 systems do not have air filters. Any computer equipment can be adversely af
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.
Metallically conductive particles can short circuit electronic components. Tape drives and some other
mechanical devices can experience failures resulting from airborne abrasive particles.
For recommendations to keep the site as free of dust and pollution as possible, consult with your heating,
ventilation, and air conditioning (HVAC) engineer or your Hewlett Packard Enterprise site preparation
specialist.

Over time, fine whiskers of pure metal can form on electroplated zinc, cadmium, or tin surfaces such as
aged raised flooring panels and supports. If these whiskers are disturbed, they can break of
airborne, possibly causing computer failures or operational interruptions. This metallic particulate
contamination is a relatively rare but possible threat. Kits are available to test for metallic particulate
contamination, or you can request that your site preparation specialist or HVAC engineer test the site for
contamination before installing any electronic equipment.
Space for receiving and unpacking the system
WARNING: A fully populated rack is unstable when moving down the unloading ramp from its
shipping pallet. A falling rack can cause serious or fatal personal injury
√Verify
There is adequate space to receive and unpack the system from shipping cartons and pallets and
to remove equipment using supplied ramps. For physical dimensions of the system equipment, see
Dimensions and Weights for NS7 AC Systems on page 53
