Space And Airflow Requirements; Temperature Requirements - HPE Synergy 12000 Frame Setup And Installation Manual

Electronic Computer/Data Processing Equipment). For electrical power ratings on options, refer to the
product rating label or the user documentation supplied with that option.
WARNING: To reduce the risk of personal injury, fire, or damage to the equipment, do not overload
the AC supply branch circuit that provides power to the rack. Consult the electrical authority having
jurisdiction over wiring and installation requirements of your facility.
CAUTION: Protect the storage module from power fluctuations and temporary interruptions with a
regulating UPS. This device protects the hardware from damage caused by power surges and
voltage spikes and keeps the storage module in operation during a power failure.

Space and airflow requirements

CAUTION: In high-density configurations, the HPE 11000 G2 Series Rack Airflow Optimization Kit
(BW930A) should be installed to prevent airflow from the rear of the rack to the front the rack via
gaps in the rack frame.
To enable servicing and ensure adequate airflow, observe the following spatial requirements when
deciding where to install a Hewlett Packard Enterprise-branded, Compaq-branded, Telco, or third-party
rack:
• Leave a minimum clearance of 63.5 cm (25 in) in front of the rack.
• Leave a minimum clearance of 76.2 cm (30 in) in back of the rack.
• Leave a minimum clearance of 121.9 cm (48 in) from the back of the rack to the rear of another rack or
row of racks.
Compute modules draw cool air in through the front and expel warm air through the rear of the frame.
Therefore, the front of the frame must be adequately ventilated to enable ambient room air to enter the
frame, and the rear of the frame must be adequately ventilated to enable the warm air to escape from the
frame.
Hewlett Packard Enterprise Advanced Series Racks, Hewlett Packard Enterprise Series Racks, and
Hewlett Packard Enterprise Standard Series Racks provide proper compute module cooling through flow-
through perforations in the front and rear doors that provide 65 percent open area for ventilation.
If the front of the rack is not completely filled with components, the remaining gaps between the
components can cause changes in the airflow, which can adversely affect cooling within the rack. Cover
these gaps with blanking panels.
IMPORTANT: Do not block the ventilation openings.
CAUTION: Always use blanking panels to fill empty vertical spaces in the rack. This arrangement
ensures proper airflow. Using a rack without blanking panels results in improper cooling that can
lead to thermal damage.

Temperature requirements

To ensure continued safe and reliable equipment operation, install or position the rack in a well-ventilated,
climate-controlled environment.
