H3C S5810 Series Quick Start Manual page 21

S5810 series, select a proper location according to the ventilation design of your installation
environment.
The ventilation process of the S5810 series is shown in Figure 1-10. Air goes in from the air vents at
both sides of the chassis, takes the heat generated from the chassis and the power modules, and then
goes out from the exhaust vents of the turbo fan and power modules. The chassis and power modules
use separate air channels for heat dissipation. Make sure that both air channels are free of obstruction.
