1.4.3 Normalized Airflow

Proper subsystem cooling is referred to as “normalized” airflow. Normalized airflow

ensures the sufficient cooling of the subsystem and is only attained when all the

components are properly installed. Therefore, a failed component should only be hot-

swapped when a replacement is available. If a failed component is removed but not

replaced, permanent damage to the subsystem can result.
