Dual-power input: The switch can be powered by one power module, or two power modules. When both two modules are
available, the switch is powered in load-balanced state.
When the switch is powered by the dual-power modules, if the system working power is greater than the capacity of
single power module, power redundancy cannot work.
Heat Dissipation
The QSW-4600-28ТX-POE adopts turbine fans for heat dissipation, thereby ensuring normal function of the device in the
specified environment. 10 cm distance space should be reserved at both sides and the back plane of the cabinet to allow
air circulation. It is recommended to clean the device once every 3 months to avoid dust from blocking vents. Figure 1-16
shows the flow scheme of heat dissipation.
