Space and airflow requirements

To enable servicing and ensure adequate airflow, observe the following spatial requirements
when deciding where to install a rack:
Leave a minimum clearance of 63.5 cm (25.0 in) in front of the rack.
Leave a minimum clearance of 76.2 cm (30.0 in) in back of the rack.
Leave a minimum clearance of 121.9 cm (48.0 in) from the back of the rack to the rear of
another rack or row of racks.
Ensure that at least 30 cm (11.81 in) of open space is available to the right of the right hard
drive drawer to facilitate the installation and removal of hard drives.
The D6020 draws in cool air through the front door, and then expels warm air through the rear
door. Therefore, the front and rear rack doors must be ventilated adequately to enable ambient
room air to enter the cabinet, and the rear door must be ventilated adequately to enable the warm
air to escape from the cabinet.
CAUTION:
ventilation openings.
CAUTION:
the gaps between the components cause changes in airflow through the rack and across the
nodes. Cover all gaps with blanking panels to maintain proper airflow. This arrangement ensures
proper airflow. Using a rack without blanking panels results in improper cooling that can lead to
thermal damage.
The HPE Rack 10000 series rack provides proper node cooling from flow-through perforations
in the front and rear doors that provide a 64 percent open area for ventilation.
CAUTION:
rack is used, observe the following additional requirements to ensure adequate airflow and to
prevent damage to the equipment:
Front and rear doors—If the 42U rack includes closing front and rear doors, you must allow
at least 5,350 sq cm (830 sq in) of holes evenly distributed from top to bottom to permit
adequate airflow (equivalent to the required 64 percent open area for ventilation).
Side—The clearance between the installed rack component and the side panels of the rack
must be a minimum of 7 cm (2.75 in).

Temperature requirements

To ensure continued safe and reliable equipment operation, install or position the rack in a
well-ventilated, climate-controlled environment.
The maximum TMRA for most storage products is 35°C (95°F). The temperature in the cold aisle
where the rack is located must not exceed 35°C (95°F). The D6020 reports an over-temperature
condition and performs an emergency shutdown of the hard drive bays within a drawer if the
