Catalyst 9400 Series 24‑Port 10 Gigabit Ethernet Line Card

Product Description

The Cisco C9400‑LC‑24XS is a high‑performance modular line card designed for use with Cisco Systems Catalyst 9400 Series switches. This line card provides 24 high‑speed 10 Gigabit Ethernet (SFP+) ports that are also backward‑compatible with 1 Gbps SFP modules, offering flexible fiber connectivity for enterprise access, aggregation, or backbone deployments.

By supporting both 10 Gbps and 1 Gbps speeds on the same port set, the C9400‑LC‑24XS enables phased network upgrades and seamless integration with existing optical infrastructures, making it ideal for high‑throughput campus cores, distribution layers, or fiber access expansions within modular Catalyst 9400 chassis.

Key Features

24 × SFP+ / SFP Fiber Ports — Each port supports 10 Gbps speeds for high‑performance links and is also backward compatible with 1 Gbps SFP optics for flexible deployment.

Dual‑Speed Capability — Ports operate as either 10 G or 1 G depending on optics installed, supporting phased migration strategies.

Modular Hot‑Swappable Design — Fits into the Catalyst 9400 chassis slot and can be installed or replaced without powering down the system.

Enterprise Fiber Connectivity — Ideal for high‑bandwidth fiber aggregation, uplinks to core layers, or backbone links in campus networks.

Broad Optics Support — Compatible with a variety of Cisco and industry‑standard SFP+ and SFP transceivers for short‑ and long‑distance fiber connectivity.

High Line‑Rate Performance — Delivers wire‑speed forwarding across all 24 ports for demanding enterprise traffic loads.

Supports Enterprise Features — Works with Cisco IOS‑XE software and supports configuration, VLANs, QoS, and security features of the catalyst platform (supervisor & software dependent).
