1.4.3 Normalized Airflow
Proper cooling is referred to as “normalized” airflow. Normalized airflow ensures the sufficient cooling within the subsystem and is only attained when all components are properly installed. Therefore, a failed component should only be removed when a replacement is available. If a failed component is removed but not replaced, airflow will disrupted and permanent damage to the subsystem can result.
