Space and airflow requirements
To allow for servicing and adequate airflow, observe the following space and airflow 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) behind the rack.
• Leave a minimum clearance of 121.9 cm (48.0 in) from the back of the rack to the back of another rack
or row of racks.
The HP MDS600 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: To prevent improper cooling and damage to the equipment, do not block the
ventilation openings.
When a vertical space in the rack is not populated by a server or rack component, the gaps between the
components cause changes in airflow through the rack and across the servers. Cover all gaps with blanking
panels to maintain proper airflow.
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.
The HP Rack 10000 series rack provides proper server cooling from flow-through perforations in the front
and rear doors that provide a 64-percent open area for ventilation.
CAUTION: HP has not tested or validated the MDS600 with any third-party rack. If a third-party
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 MDS600 in a
well-ventilated, climate-controlled environment.
The maximum TMRA for most MDS600 products is 35°C (95°F). The temperature in the cold isle where the
rack is located must not exceed 35°C (95°F). The MDS600 reports an over temperature condition and
