Power Supply
The RG-S2910C-48GT2XS-HP-E supports two power modules with AC or DC input. For the detailed power specification,
see the section of Power Supply for RG-S2910C-24GT2XS-HP-E.
Dual-power input: The switch can be powered by one power module, or by two power modules. When both two modules
are available, the switch is powered in the load-balanced mode.
When the switch is powered by the dual-power modules, if the system working power is greater than the
capacity of single power module, the power redundancy cannot work.
Heat Dissipation
The RG-S2910C-48GT2XS-HP-E 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 prevent dust from blocking vents.
Figure 1-8 shows the flow scheme of heat dissipation.
