SG300-10SFP 10-Port Gigabit Managed SFP Switch
RJ-45 Ethernet Ports—Use these ports to connect network devices, such
as computers, printers, and access points, to the switch.
SFP (if present)—The small form-factor pluggable (SFP) ports are
connection points for modules, so the switch can link to other switches.
These ports are also commonly referred to as miniGigaBit Interface
Converter (miniGBIC) ports. The term SFP will be used in this guide.
• SFP ports are compatible with Cisco modules MGBT1, MGBSX1,
MGBLH1, MGBLX1, MGBBX1, MFELX1, MFEFX1, MFEBX1, and MGBT1, as
well as other brands of modules.
• Some SFP interfaces are shared with one other RJ-45 port, called a
combo port. When the SFP is active, the adjacent RJ-45 port is
disabled. Combo ports are indicated by the presence of a bar on the
panel that connects them, as shown in the following example:
