Side Panel Components - D-Link Gama DGS-3000 Series Hardware Installation Manual

The AC power socket 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 Switch
automatically adjusts the power setting to any supply voltage in the range from 100 to 240 VAC at 50 to 60 Hz.
The electrical grounding point, on the back panel, and the protective ground connector in the AC power socket are
connected. We'll simply refer to this shared connection and Ground (GND). Surge protection in the Switch allows for 2
KV surges between the Line/Single-phase/Hot (L) wire and the Neutral (N) wire, 4 KV surges between the L/N wires
and Ground (GND), and 6 KV surges between the Ethernet ports and Ground (GND).
An optional external RPS can be plugged into the RPS port. When the internal power fails, this optional external RPS
will take over all the power immediately and automatically.
For more information about installing the DC power supply, refer to Power On (DC Power) on page 23.

Side Panel Components

The side panels of switches in this series contain heat vents, fans, and rack-mounting screw holes. The heat vents are
used to dissipate internal heat and facilitate internal air circulation. Do not block these openings. Leave at least 6
inches of space at the rear and sides of the Switch for proper ventilation. Without proper heat dissipation and air
circulation, system components might overheat which could lead to system failure or even severely damaged
components.
