Catalyst 9400 Series 40-Port 10G SFP+ Line Card

Product Description

The Cisco C9400-40X-A from Cisco is a high-performance 40-port 10-Gigabit Ethernet line card designed for the Catalyst 9400 modular switching platform. Built for enterprise campus core and aggregation deployments, it delivers high-density fiber connectivity, advanced Layer 2/Layer 3 capabilities, and scalable switching performance.

This module provides forty SFP+ 10-Gigabit ports for high-bandwidth uplinks, server aggregation, or distribution layer connectivity. When deployed within a Catalyst 9400 chassis, it enables organizations to scale network throughput while maintaining centralized policy control, security enforcement, and high availability.

With support for Cisco’s modular architecture, advanced QoS, segmentation, and high-speed backplane connectivity, the C9400-40X-A is engineered for large enterprise networks requiring reliable fiber switching at scale.
