D-Link DES-3250TG Standalone Layer 2 Switch 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. 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 Each side panel contains heat vents to help to dissipate heat. Figure 3-3. Side panel views of the Switch The system fans are used to dissipate heat.

Be reminded that without proper heat dissipation and air circulation, system components might overheat, which could lead to system failure. Gigabit Combo Ports In addition to the 48 10/100 Mbps ports, the Switch features two Gigabit Ethernet Combo ports. These two ports are 1000BASE-T copper ports (provided) and Mini-GBIC ports (optional). See the diagram below to view the two Mini-GBIC port modules being plugged into the Switch. Please note that although these two front panel modules can be used simultaneously, the ports must be different. The GBIC port will always have the highest priority. Figure 3-4.

Gigabit Combo Ports
In addition to the 48 10/100 Mbps ports, the Switch features two Gigabit Ethernet Combo ports. These
two ports are 1000BASE-T copper ports (provided) and Mini-GBIC ports (optional). See the diagram
below to view the two Mini-GBIC port modules being plugged into the Switch. Please note that although
these two front panel modules can be used simultaneously, the ports must be different. The GBIC port
will always have the highest priority.
