Cisco Catalyst 9400 Series 24-Port Line Card Switch Module

Overview

The Cisco C9400-LC-24XS= is a line card designed for the Catalyst 9400 Series chassis that expands your network with 24 ports capable of 1 Gigabit or 10 Gigabit Ethernet speeds. This module enhances switching capacity by simply sliding into an available slot, allowing you to upgrade without replacing the entire chassis. Each port supports up to 60 watts of Power over Ethernet, making it suitable for powering devices like wireless access points and PTZ cameras directly through the network cable.

Integrated into Cisco’s SD-Access architecture, this line card supports cloud services, IoT traffic, and policy-based security with centralized management. When fully populated in a Catalyst 9400 chassis, the system can deliver up to 9 Tbps of bandwidth, ensuring smooth handling of large file transfers, wireless aggregation, and real-time video alongside critical business applications.

Key features

• Twenty-four ports that can run at either 1G or 10G Ethernet speeds, providing flexible connectivity options.
• Plug-and-play installation that allows quick expansion of your Catalyst 9400 chassis without downtime.
• Power over Ethernet delivering up to 60 W per port, eliminating the need for separate power supplies for connected devices.
• Seamless integration with Cisco SD-Access for consistent, policy-driven network management across campus environments.
• Support for redundant supervisors and power supplies to maintain high availability and minimize network interruptions.
• Modular design enabling upgrades or replacements of line cards without shutting down the entire switch.

Key specs

• Ports: 24 x 1G/10G Ethernet
• Power over Ethernet: up to 60 W per port
• System bandwidth (with full chassis): up to 9 Tbps

Connectivity and compatibility

This line card fits directly into the Catalyst 9400 Series chassis, expanding its port count and throughput capabilities. It supports both 1 Gigabit and 10 Gigabit Ethernet connections, making it versatile for a range of network devices from standard endpoints to high-speed aggregation points. The PoE capability on every port simplifies deployment of powered devices without additional cabling or adapters.

Performance and reliability

Designed for enterprise-grade networks, this module supports redundant supervisors and power supplies to ensure continuous operation even during hardware failures. Its modular nature allows network administrators to upgrade or replace the line card independently, reducing downtime and maintaining network stability. The high system bandwidth capacity supports demanding applications such as video streaming and large data transfers without congestion.

Ideal uses and environments

This line card is well suited for large campus networks, enterprise offices, educational institutions, and retail environments where high-speed connectivity and reliable power delivery are essential. It supports environments that require centralized policy management and secure, scalable network infrastructure. Network teams looking to expand capacity while preserving existing investments will find this module a practical and cost-effective solution.
