Cooling system
The cooling system of the switch includes the air vents in the chassis, fan trays, and built-in fans of power
modules. To guarantee the performance of this cooling system, consider the ventilation design for the
installation site when you choose a fan tray assembly and plan the installation site for the switch.
Cooling system for the S9804 switch
You must install two fan trays of the same model for the S9804 switch: LSVM1S9800FAN and
LSVM2S9800FAN:
• When the LSVM1S9800FAN fan trays are used, ambient air flows in through the air vents in the fan
tray panels, circulates through the chassis and the power modules, and exhausts through the air
vents in the power module panels and port-side panel, as shown in
Figure 62 .
• When the LSVM2S9800FAN fan trays are used, ambient air flows in through the air vents in the
port-side panel, circulates through the chassis and the power modules, and exhausts through the air
vents in the fan tray panels and the power module panels, as shown in Figure 63 .
