Appendix D Cooling system
The cooling system of the switch includes air vents in the chassis, fan trays, and built-in fans of power
modules. To guarantee that this cooling system can effectively work, you must consider the site ventilation
design when you plan the installation site for the switches.
S5830V2-24S cooling system
The fan trays in the S5830V2-24S switch must be the same type: LSVM1FANSC or LSVM1FANSCB.
• When LSVM1FANSC fan trays are 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 network port side, as shown in Figure 56 .
• When LSVM1FANSCB fan trays are used, ambient air flows in through the air vents in the network
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 panels, as shown in
Figure 57 .
