Cooling system
The cooling system of an S5820X switch comprises the ventilation holes in the chassis, fan trays, and
built-in fans of hot swappable power modules. To guarantee that this cooling system can effectively work,
you must consider the ventilation design for the installation site when you plan the installation site.
S5820X-26S cooling system
The fan trays in the S5820X-26S switch must be the same type: LSWM1FANSC or LSWM1FANSCB.
• When LSWM1FANSC 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 11 .
• When LSWM1FANSCB 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 12 .
