Core Functionality & Port Specifications

The ​​C9400-LC-48T++=​​ is a ​​48-port 10GBase-T line card​​ for Cisco Catalyst 9400 Series modular chassis, delivering ​​802.3bt PoE++​​ with ​​90W per port​​. Designed for high-density power and data delivery, it supports ​​1/2.5/5/10G auto-negotiation​​, making it ideal for ​​Wi-Fi 7 APs​​, ​​4K AV systems​​, and ​​industrial IoT controllers​​ requiring simultaneous high-speed connectivity and power.

Deployment Scenarios & Use Cases

• ​​Enterprise campuses​​: Power clusters of 802.11be (Wi-Fi 7) access points with MultiGig uplinks.
• ​​Smart buildings​​: Drive digital signage, PTZ cameras, and building automation systems.
• ​​Edge compute nodes​​: Host Cisco IOx applications for localized IoT data processing.

Chassis Compatibility & Scalability

This line card slots into ​​Catalyst 9407R, 9410R, or 9436R chassis​​, scaling to ​​144x 10GBase-T ports per chassis​​. It supports ​​StackWise Virtual​​ for unified management of distributed stacks, reducing operational overhead in multi-site deployments.

Advanced Security & Traffic Segmentation

Integrated with ​​Cisco DNA Center​​, the module enforces ​​group-based policies (GBP)​​ to isolate IoT devices from critical infrastructure. ​​MACsec-256 encryption​​ secures traffic at the port level, ensuring compliance with HIPAA or GDPR requirements.

Power Efficiency & Thermal Resilience

​​EnergyWise Plus​​ dynamically allocates power based on device demand, reducing idle consumption by ​​35-50%​​ compared to fixed-power modules. The ​​front-to-back airflow​​ design aligns with hot-aisle containment, operating reliably at ​​ambient temperatures up to 45°C​​.

Licensing & Operational Simplicity

The module ships with ​​Network Essentials​​ for basic Layer 2/3 features. ​​DNA Advantage​​ unlocks SD-Access, encrypted traffic analytics, and AI-driven assurance. For legacy networks, ​​IP Base​​ supports OSPF, EIGRP, and PIM routing protocols.
