Cooling system
The cooling system of the S5830 switch comprises the air vents in the chassis, fan tray, and built-in fans
of power modules. To guarantee the performance of this cooling system, you must consider the
ventilation design for the installation site when you choose a fan tray assembly and plan the installation
site for the S5830 switch.
Cooling system of the S5830-52SC
• When an LSVM152SCFAN fan tray is used, ambient air flows in through the air vents in the fan tray
panel and the power module panels, circulates through the chassis and the power modules, and
exhausts at the port side, as shown in Figure 53 .
• When an LSVM252SCFAN fan tray is used, ambient air flows in through the air vents in the
port-side panel and the power module panels, circulates through the chassis and the power
modules, and exhausts through the air vents in the fan tray panel, as shown in
Figure 54 .
