Airflow |
|
1These
specifications refer to a sytem that is fully extended from the rack for
service. When in normal operation, there are no side clearance requirements
for the server as the air flow is from the front to rear. However, make
sure that any front or back cabinet doors are 63% open to allow adequate
airflow. This can be accomplished by removing the doors, or ensuring that
the doors have a perforated pattern that provides a 63% open area. See
Site Planning Guide for Entry Level Servers
for more details. |
