Figure 1–3 Rear panel view of a DES-3810 Series Switch
The AC power connector is a standard three-pronged connector that supports the power cord. Plug-in the female
connector of the provided power cord into this socket, and the male side of the cord into a power outlet. The DES-
3810 Series automatically adjusts the power setting to any supply voltage in the range from 100 ~ 240 VAC at 50 ~ 60
Hz. In addition, an optional external Redundant Power Supply (DPS-200) can be plugged into the connector displayed
above. When the internal power fails, this optional external RPS will take over all the power immediately and
automatically.
Side Panel Description
The system heat vents located on each side dissipate heat. Do not block these openings. Leave at least 6 inches of
space at the rear and sides of the Switch for proper ventilation. Be reminded that without proper heat dissipation and
air circulation, system components might overheat, which could lead to system failure or even severely damage
components.
