Description
The Cisco C9400-LC-48U is a high-density 48-port UPOE line card designed for Cisco Catalyst 9400 Series modular switches, delivering reliable Gigabit Ethernet connectivity with integrated power for modern enterprise networks. Featuring forty-eight 10/100/1000 Mbps RJ-45 ports, this line card supports PoE, PoE+, and Cisco Universal Power over Ethernet (UPOE), providing up to 60W per port to power a wide range of connected devices.
Built for scalable campus and branch deployments, the C9400-LC-48U enables centralized power delivery for IP phones, wireless access points, surveillance cameras, video endpoints, and other UPOE-enabled devices—eliminating the need for additional electrical infrastructure. Its non-blocking architecture ensures consistent performance across all ports, while support for advanced security features and jumbo frames makes it ideal for high-throughput enterprise environments.
As part of the Catalyst 9400 modular ecosystem, this line card offers long-term investment protection, seamless integration with Cisco IOS XE, and enterprise-class reliability for mission-critical access layer deployments.
