Node Cooling

A fan assembly with three six-inch 48 VDC fans is mounted on a tray at the rear of the BPX switch shelf
(see Figure 2-2). Air for cooling the cards is drawn through an air intake grille located at the bottom in
the front of the enclosure. Air passes up between the vertically-mounted cards and exhausts at the top,
rear of the chassis.
All unused slots in the front are filled with blank faceplates to channel airflow properly.
