C9400-LC-24XY Description
C9400-LC-24XY, also known as Cisco Catalyst 9400 24-Port 25G SFP28 line card, enables ultra-high-speed fiber aggregation for Catalyst 9400 modular switches. This line card supports 20 ports of 25GbE SFP28 and 4 ports of 10GbE SFP+, with all ports capable of auto-negotiating down to 10GbE or 1GbE SFP for maximum flexibility. Designed for next-generation enterprise, data center, and service provider environments, the C9400-LC-24XY SFP28 card delivers up to 480Gbps line-rate throughput per slot with C9400X-SUP-2XL supervisors. The card features robust MACsec-256 security, jumbo frame support, and hot-swap capability, making it the ideal 25G/10G fiber module for bandwidth-intensive aggregation and high-performance core deployments. It is an essential component for organizations looking to future-proof their network with scalable, flexible fiber connectivity.

On the C9400-LC-24XY line card:
- The figure illustrates four distinct port groups.
- In each port group:
- 4 ports support 25 Gbps connectivity.
- 1 port supports 10 Gbps connectivity.
- The total bandwidth per group is up to 120 Gbps.
- As a result, one port per group remains unused to stay within the bandwidth limit.
