•
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.
HP BladeSystem servers draw cool air in through the front and expel warm air through the rear of the
enclosure. Therefore, the front of the rack enclosure must be adequately ventilated to enable ambient
room air to enter the enclosure, and the rear of the enclosure must be adequately ventilated to enable the
warm air to escape from the enclosure.
IMPORTANT:
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.
CAUTION:
arrangement ensures proper airflow. Using a rack without blanking panels results in improper
cooling that can lead to thermal damage.
In high density configurations, the HP 10000 Series Rack Airflow Optimization Kit (AF090A) should be
installed to prevent airflow from the rear of the rack to the front the rack via gaps in the rack frame.
HP 10000 Series and 10000 G2 Series racks provide proper server cooling from flow-through
perforations in the front and rear doors that provide 65 percent open area for ventilation.
CAUTION:
proper airflow. Using an enclosure without the proper blanks 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.
The operating temperature inside the rack is always higher than the room temperature and is dependent
on the configuration of equipment in the rack. Check the TMRA for each piece of equipment before
installation.
CAUTION:
• Do not permit optional equipment to impede airflow around the enclosure or to increase the
internal rack temperature beyond the maximum allowable limits.
Do not exceed the manufacturer's TMRA.

Power requirements

Installation of this equipment must comply with local and regional electrical regulations governing the
installation of IT equipment by licensed electricians. This equipment is designed to operate in installations
covered by NFPA 70, 1999 Edition (National Electric Code) and NFPA-75, 1992 (code for Protection of
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.
Do not block the ventilation openings.
Always use blanking panels to fill empty vertical spaces in the rack. This
