Core Functionality & Port Configuration

The ​​C9400-LC-48HX++=​​ is a ​​48-port MultiGigabit line card​​ for Cisco Catalyst 9400 Series chassis, delivering ​​1/2.5/5/10GBase-T speeds​​ with ​​802.3bt PoE++​​ support. Each port provides ​​up to 90W​​, making it ideal for ​​Wi-Fi 7 APs​​, ​​pan-tilt-zoom cameras​​, and ​​industrial IoT devices​​ demanding high power and bandwidth.

Deployment Flexibility & Use Cases

• ​​High-density wireless campuses​​: Power 802.11be (Wi-Fi 7) APs requiring MultiGig uplinks and 90W PoE++.
• ​​Smart buildings​​: Connect and power building automation systems, digital signage, and HD surveillance.
• ​​Edge compute hubs​​: Host Cisco IOx applications for localized processing of IoT sensor data.

Chassis Compatibility & Scalability

Designed for ​​Catalyst 9407R, 9410R, or 9436R chassis​​, this line card scales port density to ​​144x MultiGig ports per chassis​​ when fully populated. It supports ​​StackWise Virtual​​ for unified management of distributed stacks, reducing operational complexity in multi-site deployments.

Advanced Security & Traffic Management

Integrated with ​​Cisco DNA Center​​, the module enforces ​​zero-trust segmentation​​, isolating IoT devices from critical infrastructure. ​​MACsec-256 encryption​​ secures traffic at the port level, meeting compliance standards for sectors like healthcare and finance.

Power Efficiency & Thermal Design

​​EnergyWise Plus​​ dynamically allocates power based on device demand, reducing idle consumption by ​​40-60%​​. The card’s ​​reverse airflow design​​ aligns with hot-aisle containment setups, operating reliably at ​​ambient temperatures up to 45°C​​.

Licensing & Operational Considerations

The module ships with ​​Network Essentials​​ for basic Layer 2/3 features. ​​DNA Advantage​​ is required for SD-Access, encrypted traffic analytics, and AI-driven network assurance. For legacy environments, ​​IP Base​​ enables OSPFv3 and BGP routing.

Procurement & Firmware Requirements

For verified pricing and availability, refer to [“C9400-LC-48HX++=” link to (https://itmall.sale/product-category/cisco/). Ensure chassis supervisors run ​​IOS XE 17.12.1+​​ to unlock full PoE++ and MACsec-256 capabilities.

Why This Line Card Excels in Power-Intensive Deployments

Having integrated Catalyst 9400 Series in large-scale IoT and wireless rollouts, the ​​C9400-LC-48HX++=​​ eliminates midspan PoE injectors while future-proofing for Wi-Fi 7’s bandwidth demands. Its 90W per port simplifies power budgeting for clusters of PTZ cameras or AV systems, and StackWise Virtual streamlines multi-site management. For enterprises prioritizing scalability without chassis sprawl, this module is a pragmatic choice.
