NOTE:
Each of the 96G model and 96G TAA model switches comes with the fan tray slot covered by a filler
panel and the power supply slots installed with filler modules. In this figure, two 650W AC power

Cooling system
The cooling system of the switch comprises the air vents in the chassis, fan tray, and built-in fans of
power supplies. 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.

•
When a back-to-front airflow fan tray (JC692A) is used, ambient air flows in through the air
vents in the fan tray panel and the power supply panels, circulates through the chassis and the
power supplies, and exhausts at the port side, as shown in
Figure 52
