In a multi-building enterprise campus, network architects deploy the C9400-LC-24S Cisco Catalyst 9400 Series 24-Port 1 Gigabit Ethernet (SFP) line card as the primary distribution uplink to the core. By aggregating 24 fiber SFP links per chassis, IT teams achieve high-density connectivity, simplified fiber management and non-stop forwarding. The outcome is predictable, scalable campus performance with built-in redundancy and streamlined operations.
In a virtualized data center, operations engineers install the C9400-LC-24S into Catalyst 9400 switches acting as leaf nodes to connect hyperconverged server clusters via 1 Gbps SFP ports. The dense 24-port fiber capacity reduces cabling complexity, ensures consistent low-latency throughput and accelerates server provisioning. The result is optimized resource utilization, rapid service rollout and simplified lifecycle management.
On a smart factory floor, security teams integrate the C9400-LC-24S Cisco Catalyst 9400 Series 24-Port 1 Gigabit Ethernet (SFP) line card to isolate and segment IoT devices, industrial controllers and OT VLANs. Leveraging Cisco DNA Center policy enforcement and 24 dedicated fiber SFP links, administrators gain granular micro-segmentation and real-time threat containment. This delivers enhanced cyber-resilience, regulatory compliance and minimal production downtime.

This module is reliable and efficient. It provides high-performance 1GE Ethernet connectivity with easy integration into our Cisco setup.
The C9400-LC-24S module is a great addition to our network. It's cost-effective and provides consistent connectivity for our routine operations.
The 24-port 1GE module delivers excellent performance for our lower-bandwidth needs. It's a stable, reliable solution for expanding our infrastructure.
The C9400-LC-24S is a modular line card for the Cisco Catalyst 9400 Series chassis, providing 24 fixed 1 Gbps SFP ports for uplink and access deployments.
The C9400-LC-24S supports Cisco 1G SFP modules such as GLC-SX-MMD, GLC-LH-SMD, GLC-EX-SMD and other Cisco-qualified 1G optics.
Each C9400-LC-24S delivers up to 48 Gbps of aggregate throughput and supports a forwarding rate of 71.4 Mpps for 64-byte packets.
The C9400-LC-24S line card itself does not supply PoE; PoE capabilities are provided by separate access modules designed for the 9400 chassis.
A fully populated Catalyst 9400 chassis can accommodate up to seven line cards, depending on the chassis model (C9400-24T or C9400-48T).
Cisco Catalyst 9400 Series uses StackWise Virtual technology to logically stack multiple chassis, including C9400-LC-24S line cards, into a single logical switch.
The C9400-LC-24S relies on the 9400 chassis power supplies; Cisco recommends dual redundant AC or DC PSUs sized per chassis configuration.
Cisco DNA Essentials or Advantage licensing on the Catalyst 9400 chassis unlocks advanced automation, security and analytics for the C9400-LC-24S.
The C9400-LC-24S can be managed via Cisco DNA Center, Cisco Prime Infrastructure or CLI/REST APIs through the Catalyst 9400 chassis supervisor engine.
