Gigabit Combo Ports
The DES-1210 Series features either two or four Gigabit Ethernet Combo ports. These ports are 1000BASE-
T copper ports (optional) and Small Form Factor Portable (SFP) ports (optional). See the diagram below to
view the two SFP 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 SFP port will always have the
highest priority.

Figure 1-12. Installing the SFP Module
The Switch is equipped with SFP ports, which 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. For a full list of
supported SFP transceivers, for this switch series, refer to the Appendix-E.
