The DGS-3627G contains twenty-four 1000Mbps SFP (Small Form Factor Portable) ports, in addition to four 1000BASE-T
located on the front panel. The DGS-3612 contains twelve 10/100/1000BASE-T ports, all of which are Auto MDI-X/MDI-II
convertible ports that can be used for uplinking to another switch, and four 100/1000Mbps SFP (Small Form Factor Portable)
ports. 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), DEM-310GT (1000BASE-LX), DEM-311GT
(1000BASE-SX), DEM-312GT2 (1000BASE-SX), DEM-314GT (1000BASE-LH), DEM-315GT (1000BASE-ZX), DEM-
330T/R (WDM Transceiver) and the DEM-331T/R (WDM Transceiver) transceivers. These ports are referred to as "combo"
ports. That means both the SFP ports and the 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.
The DGS-3627, DGS-3627G, and the DGS-3650 also contain open slots in the rear of the Switch, which are used to add optional
single-port 10GE modules. Two available slots reside within the DGS-3650, while the DGS-3627 and DGS-3627G both contain
three slots. These modules, the DEM-410CX CX4 and the DEM-410X XFP, are IEEE 802.3ae and IEEE 802.3ak compliant and
support full-duplex mode only. More information will be provided on these modules later in this manual.
This Switch enables the network to use some of the most demanding multimedia and imaging applications concurrently with other
user applications without creating bottlenecks. The built-in console interface can be used to configure the Switch's settings for
priority queuing, VLANs, and port trunk groups, port monitoring, and port speed.
