The Cisco C9400-LC-48U is a 48-port Gigabit Ethernet line card for the Cisco Catalyst 9400 Series modular access platform. Designed for enterprise access deployments, the module supports 10/100/1000 Mbit/s speeds and integrates with Cisco Digital Network Architecture (Cisco DNA) and Software Defined Access (SD-Access) to simplify wired access, enable network segmentation and apply group-based policies. The line card supports PoE, PoE+ and Cisco UPOE power delivery, providing up to 60W per port to power high-demand devices while fitting into the Catalyst 9400 chassis for scalable access-layer switching.

Advantages

This 48-port Gigabit Ethernet module delivers high port density in a compact form factor and is compatible with Cisco Catalyst 9400 Series features such as SD-Access, network virtualization, and unified wired/wireless management. It supports up to 60W per port (Cisco UPOE) to power IP phones, cameras, wireless access points and other PoE devices without extra electrical circuits. The module offers enterprise-grade reliability and integrates with the platform’s high-availability and redundant power options to reduce downtime and protect network investment.

Suitable for

• Enterprise access layer switch deployments in campus networks
• Environments requiring PoE/PoE+/UPOE for access devices (APs, cameras, phones)
• Networks using Cisco DNA / SD-Access for automated policy and segmentation
• Closet or rack installations where compact depth and high port density are needed

How to use

Install the C9400-LC-48U into a compatible Cisco Catalyst 9400 Series chassis following Cisco installation procedures and safety guidelines. Connect upstream uplinks and configure the module in the chassis through the platform’s management interface. Assign VLANs, power settings and group-based policies using Cisco DNA Center or the Catalyst command-line/management tools. Connect end devices to the 48 Gigabit ports and verify link status and power delivery for PoE devices.

Recommendations

Deploy the line card in a properly ventilated, climate-controlled rack or closet and use the Catalyst 9400 platform’s redundant power and high-availability features for critical networks. Use Cisco DNA Center for centralized policy, automation and monitoring to maximize the benefits of SD-Access and PoE power management.
