Chapter 1 Product Overview
Front Panel
Uplink Ports
The switch supports four SFP module slots that provide uplink ports to connect to other devices.
Depending upon the switch model, the uplink port support for SFP and SFP+ modules is:
• Four slots supporting only 1-Gigabit SFP modules.
• Two slots (left side) supporting only 1-Gigabit SFP modules and two slots (right side) supporting
either 10-Gigabit SFP+ modules or 1-Gigabit SFP modules.
• Four slots supporting either 1-Gigabit SFP modules or 10-Gigabit SFP+ modules.
For more information, see “Catalyst 3650 Switch Models” in Table 1-1 on page 1-1. For cable
specifications, see Appendix B, “Connector and Cable Specifications.”
Note If you insert an SFP+ module in an SFP module slot, the SFP+ module slot does not operate, and the
switch logs an error message. SFP modules can operate in SFP+ module slots.
SFP and SFP+ Modules
The SFP and SFP+ modules provide copper or fiber-optic connections to other devices. These
transceiver modules are field replaceable, and provide the uplink interfaces when installed in an SFP
module slot. The SFP modules have LC connectors for fiber-optic connections or RJ-45 connectors for
copper connections.
Use only Cisco SFP and SFP+ modules on the switch. For the latest information about supported
SFP/SFP+ modules, refer to the Cisco Transceiver Modules Compatibility Matrix documentation at:
http://www.cisco.com/en/US/products/hw/modules/ps5455/products_device_support_tables_list.html
For information about SFP modules, see your SFP module documentation and the “Installing SFP and
SFP+ Modules” section on page 2-17. 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 1-4 shows the switch
LEDs and the Mode button that you use to select a port mode.
