SFP Modules and Alternative Wiring

The Catalyst 4948 switches have four ports that can be configured with any combination of SFP modules with LC connectors, as shown in Figure 4-2. The interface configuration mode command media-type sfprj45 can be used to configure the media type for these ports in the switch software and determines whether the SFP or the RJ-45 connector is used. The default is SFP.
