Description
The Cisco Catalyst 9400 Series 48-Port 10G Multigigabit Data Line Card is a high-performance copper access module designed for modern campus and enterprise networks. Delivering non-blocking 10GBASE-T connectivity with backward compatibility for 5G, 2.5G, 1G, and 100 Mbps speeds, this line card enables seamless migration to higher-bandwidth endpoints over existing cabling.
Built for data-only deployments, the C9400-LC-48TX supports advanced security features such as hardware-based MACsec, Energy Efficient Ethernet, and jumbo frames up to 9216 bytes. When paired with Catalyst 9400 Series chassis and Supervisor Engine 2 or 2XL, it delivers high slot bandwidth and predictable performance for aggregation, access, and branch deployments.
Ideal for environments requiring dense 10G copper connectivity, this spare line card provides scalable performance, long-term investment protection, and seamless integration within Cisco Catalyst 9400 modular switching platforms.
