Side Panels; Gigabit Combo Ports - D-Link DES-3250TG User Manual

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.

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.
