For more information about the Cisco TwinGig Converter Module, see the “Installing X2 Transceiver
and Converter Modules” section on page 2-12 . For cable specifications, see Appendix B, “Connector
and Cable Specifications.”
SFP Modules
The Gigabit Ethernet SFP modules connect to other devices and provide uplink interfaces when inserted
in an SFP module slot. The SFP modules have LC connectors for fiber-optic connections or RJ-45
connectors for copper connections. You can use any combination of these field-replaceable modules:
•
1000BASE-SX
• 1000BASE-T
The Catalyst 2350 switch supports the SFP module patch cable, a 0.5-meter, passive copper cable with
SFP module connectors at each end. The patch cable can connect two Catalyst 2350 switches in a
cascaded configuration.
For more information about SFP modules, see your SFP module documentation and the “Installing SFP
Modules” section on page 2-14 . For cable specifications, see Appendix B, “Connector and Cable
Specifications.”
LEDs
You can use the switch LEDs to monitor switch activity and its performance. Figure 1-2 shows the switch
LEDs and the Mode button that you use to select one of the port modes.
