Front Panel Description
For information about the network modules, see the
“Installing a Network Module in the Switch” section
on page 2-22
. For cable specifications, see
Appendix B, “Connector and Cable Specifications.”
SFP and SFP+ Modules
The SFP and SFP+ modules provide copper or fiber-optic connections to other devices. These
transceiver modules are field-replaceable, providing 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 modules on the switch.
Note
The (downlink) SFP module slots on the Catalyst 3750-X-12S and Catalyst 3750-X-24S switch front
panel support any combination of standard SFP modules. SFP+ modules are not supported.
