Planning the installation 7
•
Leave a minimum clearance of 121.9 cm (48.0 in) in front of the rack and between rows of racks.
•
Leave a minimum clearance of 76.2 cm (30.0 in) in back of the rack for a single row of racks or after
the final row of racks.
Hewlett Packard Enterprise Rack products 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:
Do not block the ventilation openings.
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:
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.
Racks provide proper server cooling from flow-through perforations in the front and rear doors that
provide a 65% open area for ventilation.
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:
To reduce the risk of damage to the equipment when installing third-party options:
•
Do not permit optional equipment to impede airflow around the chassis 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.
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 chassis 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 chassis in operation during a power failure.
