The Cisco WS-X6904-40G-2T is a high-performance switch module for the Catalyst 6500 Series (compatible with Supervisor Engine 2T). It provides four 40 Gigabit Ethernet Fiber ports, each capable of accepting a 40 Gigabit Ethernet C Form-Factor Pluggable (CFP) optics module (CFP-40G-LR4 or CFP-40G-SR4). Alternatively, each port can be converted to four 10 Gigabit Ethernet ports using a FourX adapter, allowing for up to 16x 10GE ports. The module is equipped with the WS-F6K-DFC4-E Forwarding Engine for distributed forwarding, supporting advanced features like QoS prioritization, Virtual Switch Link (VSL) on all ports, and hardware-based security features like Cisco TrustSec and MACsec encryption. It is designed for campus, data center, and service provider core applications requiring high-density 10GE and 40GE transport.
