C9400-LC-48TX Description
C9400-LC-48TX, also called Cisco Catalyst 9400 48-Port 10G multigigabit data line card, is designed for high-speed, copper-based network aggregation within Catalyst 9400 modular switches. This non-PoE module supports 48 multigigabit RJ-45 ports, each operating at 10G, 5G, 2.5G, 1G, or 100M for maximum deployment flexibility. The C9400-LC-48TX delivers up to 480Gbps line-rate throughput per slot with C9400X-SUP-2XL/2 supervisors, making it ideal for bandwidth-intensive campus LAN and enterprise core environments. This line card supports jumbo frames, MACsec-256 encryption, hot-swappable installation, and energy-efficient Ethernet, providing reliable, secure, and scalable 10GBASE-T performance for modern networks.
