As the premier modular multilayer Cisco switch for integrated data center switching, the Cisco Catalyst 6500 Series now offers a new, high-performance 48-port 10/100/1000 Ethernet over copper module designed specifically for use with the Cisco Catalyst 6500 Series Supervisor Engine 720 in data center and distribution layer deployments.

The WS-X6748-GE-TX features a 40-Gbps interconnection to the Cisco Catalyst 6500 Series Supervisor Engine 720's switch fabric-ideal for high-demand, high-density Gigabit Ethernet requirements across all 48 ports.

Other Key Features include:

· Up to 386 high-performance 10/100/1000 Ethernet over copper ports in a single Cisco Catalyst 6500 Series chassis

· Flexible, scalable, field-upgradable daughter card options to support full locally distributed forwarding through the DFC3A for investment protection and "pay as you grow" performance

· Jumbo frame support, up to 9000 bytes, commonly required in data centers.

· RJ-45 interfaces to support existing copper cabling infrastructures

· Future support for an integrated time-domain reflectometer for cable fault detection and ease of troubleshooting
