Switch Description
The DGS-3700 Series is equipped with unshielded twisted-pair (UTP) cable ports providing dedicated 10 or 100 Mbps
bandwidth. The DGS-3700-12 Switch has 12 UTP ports and Auto MDI-X/MDI-II convertible ports that can be used for
uplinking to another switch. T hese ports can be us ed f or connecting P Cs, printers, servers, hubs, r outers, switches
and other networking devices. The dual speed ports use standard twisted-pair cabling and are ideal for segmenting
networks into small, connected sub networks for superior performance. Each 10/100/1000BASE-T port can support up
to 200 Mbps of throughput in full-duplex mode.
In addition, the Switch has 4 SFP combo with 10/100/1000BASE-T ports. These four-gigabit combo ports are ideal for
connecting to a server or network backbone.
The D GS-3700-12G c ontains t welve 1000Mbps SFP ( Small F orm F actor P ortable) por ts, in a ddition t o four
1000BASE-T located on the front panel. The SFP combo ports are to be used with fiber-optical transceiver cabling in
order to uplink various other networking devices for a gigabit link that may span great distances. The SFP ports can
also support full-duplex transmissions, have auto-negotiation and can be used with DEM-210 (100FX-LC), DEM-211
(100FX-LC), DE M-310GT ( 1000BASE-LX), D EM-311GT ( 1000BASE-SX), D EM-312GT2 ( 1000BASE-SX), DEM-
314GT (1000BASE-LH), DEM-315GT (1000BASE-ZX), DEM-330T/R (WDM Transceiver) and the DEM-331T/R (WDM
Transceiver) t ransceivers. These por ts ar e r eferred t o as “ combo” por ts. T hat means bot h t he S FP por ts an d t he
1000BASE-T ports are numbered the same and cannot be used simultaneously. Attempting to use the ports
simultaneously will cause a link down status for the 1000BASE-T ports. SFP ports will always have priority over these
1000BASE-T ports.
These S witches en able t he net work t o us e s ome o f t he m ost dem anding m ultimedia a nd imaging applications
concurrently with other user applications without creating bottlenecks. The built-in console interface can be us ed to
configure the Switch's settings for priority queuing, VLANs, and port trunk groups, port monitoring, and port speed.
