Setup

Optimum environment

When installing the server in a rack, select a location that meets the environmental standards described in this
section.

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 in) in front of the rack.
• Leave a minimum clearance of 76.2 cm (30 in) behind the rack.
Leave a minimum clearance of 121.9 cm (48 in) from the back of the rack to the back of another rack or
•
row of racks.
Hitachi Advanced Server product draws in cool air through the front door and expel warm air through the rear
door. Therefore, the front and rear rack doors must be adequately ventilated to allow ambient room air to enter
the cabinet, and the rear door must be adequately ventilated to allow 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 vertical space in the rack is not filled 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.
