♦ The optional Gigabit Ethernet slide-in module (1000BASE-SX, 1000BASE-LX, or 1000BASE-T) contains one port
for connecting to another 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. Supported
input voltages range from 100 ~ 240 VAC at 50 ~ 60 Hz.
Side Panels
The right side panel of the Switch contains two system fans (see the top part of the diagram below). The left side panel
contains heat vents.

♦ The system fans are used to dissipate heat. The sides of the system also provide heat vents to serve the same
purpose. Do not block these openings, and 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.
Optional Plug-in Modules
The DES-3225G 24-port NWay Ethernet Switch is able to accommodate a range of plug-in modules in order to increase
functionality and performance.
