With the ventilation system, the heat generated from the chassisand the power modules can be dissipated in time to ensure the system stability. When installing theS5810 series, select a proper location according to the ventilation design of your installationenvironment.The ventilation process of the S5810 series is shown in Figure 1-10. Air goes in from the air vents atboth sides of the chassis, takes the heat generated from the chassis and the power modules, and thengoes out from the exhaust vents of the turbo fan and power modules. The chassis and power modulesuse separate air channels for heat dissipation. Make sure that both air channels are free of obstruction.Figure 1-10 Ventilation process of the S5810 series(2)(3) (4)(2)(1)(1) Front panel (2) Air vents at both side of the chassis(3) Air exhaust vent of the turbo fan (4) Air exhaust vents of the power modulesThe turbo fan model supported by the S5810 series is LSWM1BFAN.
