Core Functionality of the C9400-LC-24XY++=
The Cisco C9400-LC-24XY++= is a high-density line card engineered for the Catalyst 9400 Series modular switches, delivering 24x 10/25G MultiGigabit Ethernet ports and 4x 40/100G QSFP28 uplinks. Designed for enterprise core and data center deployments, it combines ultra-low latency with scalable power efficiency, making it suitable for environments demanding high-throughput traffic and future-ready adaptability. The “++=” suffix signifies a premium licensing tier with advanced features like Cisco DNA Assurance and Full Stack Observability (FSO).

Technical Breakdown
- Port Configuration: 24x 10/25G MultiGig ports (RJ45/SFP28) + 4x 40/100G uplinks, enabling flexible spine-leaf architectures or high-speed server connectivity.
- Performance: Built on Cisco’s Cloud Scale ASIC, it supports 1.2 Tbps per-slot bandwidth and MACsec encryption for secure data transit.
- Scalability: Integrates with Cisco StackWise Virtual for multi-chassis link aggregation, simplifying management across distributed campuses.
- Energy Efficiency: Dynamic Power Sharing allocates up to 90W per MultiGig port (UPOE++) while reducing idle power consumption by 30%.
――――――――――――
Compatibility Requirements
This line card is exclusive to the Catalyst 9400 chassis (e.g., C9407R, C9410R) and requires Cisco IOS-XE 17.12 or later. It does not function in legacy platforms like the Catalyst 9300 or 4500 Series. Ensure chassis power supplies meet 4200W minimum for full UPOE++ utilization.
――――――――――――
Key Deployment Scenarios
- Data Center Fabric: Supports NVMe-over-Fabrics and AI/ML workloads with 100G uplinks for east-west traffic.
- Enterprise Core: Handles VoIP, videoconferencing, and zero-trust segmentation at scale.
- Smart Cities/Metro Networks: Powers IoT gateways and edge compute nodes with UPOE++ for outdoor devices.

Practical Analysis
The C9400-LC-24XY++= is a game-changer for organizations scaling hybrid cloud or AI infrastructure, but its complexity demands skilled network engineers. While its 100G uplinks and UPOE++ justify the cost for high-density use cases, smaller businesses may find it overkill. Prioritize this line card if your strategy includes intent-based networking or multi-domain automation—otherwise, simpler alternatives could suffice.
