Chapter 1 Product Overview
Other Features
10/100/1000 Ports
The 10/100/1000 Ethernet ports use standard RJ-45 connectors with Ethernet pinouts. The maximum
cable length is 328 feet (100 meters). The 100BASE-TX and 1000BASE-T traffic requires Category
5,
Category
5e, or Category 6 unshielded twisted pair (UTP) cable. The 10BASE-T traffic can use
Category
3 or Category 4 UTP cable.
For more information about the 10/100/1000 Ethernet port connections and specifications, see the
Connecting to the 10/100/1000 Ports, page 2-22, and Appendix B, “Connector and Cable
Specifications.”
10-Gigabit Ethernet Module Slots
The 10-Gigabit Ethernet module slots are used for uplink connections to other switches and routers.
The
module slots operate in full-duplex mode. The CBS3120X uses the hot-swappable Cisco X2
transceiver modules and the Cisco TwinGig Converter Module. The CBS3120G uses only the
Cisco
TwinGig Converter Module.
These X2 transceiver modules are supported on the CBS3120X switch module:
• CX4
• LX4
• SR
• LRM
For the latest information about the supported X2 transceiver modules, see the switch release notes on
Cisco.com at this location:

For more information about the 10-Gigabit Ethernet module slots, see the “Installing Devices in the
10-Gigabit Ethernet Slots” section on page 2-17. For cable specifications, see Appendix B, “Connector
and Cable Specifications.”
Cisco TwinGig Converter Module
The Cisco TwinGig Converter Module (model CVR-X2-SFP), also known as the converter module, has
two small form-factor pluggable (SFP) module slots that convert the 10-Gigabit slot into a dual
SFP
module interface to establish Gigabit uplinks to network devices. The SFP modules have
LC
connectors for fiber-optic connections or RJ-45 connectors for copper connections. These SFP
modules are supported:
• 1000BASE-SX
• 1000BASE-T
For more information about the SFP modules, refer to your SFP module documentation. For the latest
information about the supported SFP transceiver modules, see the switch release notes on Cisco.com at
this location:
