*These 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.
