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:

http://www.cisco.com/en/US/products/ps6748/tsd_products_support_series_home.html

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:

http://www.cisco.com/en/US/products/ps6748/tsd_products_support_series_home.html

For more information about the Cisco TwinGig Converter Module, see the “Installing X2 Transceiver Modules and Cisco Converter Modules” section on page 2-18. For cable specifications, see Appendix B, “Connector and Cable Specifications.”
