Abstract: A system includes a chassis having a longitudinal axis defined therethrough and an upper airflow chamber, a central airflow chamber, and a lower airflow chamber formed longitudinally therethrough, a midplane secured within the chassis in a direction perpendicular to the longitudinal axis defined through the chassis, in which the midplane defines a front portion and a rear portion within the chassis, and wherein the midplane is configured to allow airflow therethrough, and a first printed circuit board disposed within the rear portion of the chassis in the upper airflow chamber, the first printed circuit board having a first end, a second end, and an opening formed therethrough, in which the first end of the first printed circuit board is operatively coupled to the midplane.
