(1) Power module air vents

(2) Fan tray air vents

(3) Air vents in the switch side

(4) Port side air vents

IMPORTANT:

The chassis and the power modules use separate air aisles. Make sure both aisles are not blocked.

11.2 Cooling system of the QX-S5524GT-4X2Q and

QX-S5548GT-4X2Q

The QX-S5524GT-4X2Q and QX-S5548GT-4X2Q use fixed fan trays and left-to-right aisles
for air ventilation. Ambient air flows in through the air vents in the left side panel, circulates
through the chassis and the power modules, and exhausts through the air vents in the right
side panel and air vents of the power module fan trays, as shown in Figure 11-3.

Figure 11-3

Airflow through the QX-S5524GT-4X2Q and QX-S5548GT-4X2Q

IMPORTANT:

The chassis and the power modules use separate air aisles. Make sure both aisles are not blocked.
