The DGS-3700 Series are layer 2 Gigabit Ethernet switches and members of the D-Link Switch family. The following
manual describes the installation, maintenance and configurations concerning the DGS-3700-12 and DGS-3700-12G
switches. Please take note that if this device was purchased outside of Europe, certain cosmetic differences between
the actual switch and images in this document will be apparent to the reader, such as the faceplate and the manual
cover.
NOTE: For the remainder of this manual, the DGS-3700-12 and DGS-3700-12G switches will
be referred to as simply the Switch or the DGS-3700 Series.
Gigabit Ethernet Technology
Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet structure, format, and support for
CSMA/CD protocol, full duplex, flow control, and management objects, but with a tenfold increase in theoretical
throughput over 100Mbps Fast Ethernet and a one hundred-fold increase over 10Mbps Ethernet. Since it is
compatible with all 10Mbps and 100Mbps Ethernet environments, Gigabit Ethernet provides a straightforward upgrade
without wasting a company's existing investment in hardware, software, and trained personnel.
The increased speed and extra bandwidth offered by Gigabit Ethernet are essential to coping with the network
bottlenecks that frequently develop as computers and their busses get faster and more users using applications that
generate more traffic. Upgrading key components, such as your backbone and servers to Gigabit Ethernet can greatly
improve network response times as well as significantly speed up the traffic between your sub networks.
Gigabit Ethernet enables fast optical fiber connections to support video conferencing, complex imaging, and similar
data-intensive applications. Likewise, since data transfers occur 10 times faster than Fast Ethernet, servers outfitted
with Gigabit Ethernet NIC's are able to perform 10 times the number of operations in the same amount of time.
In addition, the phenomenal bandwidth delivered by Gigabit Ethernet is the most cost-effective method to take
advantage of today and tomorrow's rapidly improving switching and routing internetworking technologies.
