Introduction to the C9400-LC-48UX++=
The Cisco C9400-LC-48UX++= is a high-density, multi-rate line card for the Catalyst 9400 Series chassis, offering 48x 1/2.5/5/10G MultiGig Ethernet ports and 12x 40/100G QSFP28 uplinks. Designed for hyper-converged infrastructure and high-performance enterprise cores, it combines ultra-high PoE++ capacity with Cisco DNA Center automation, making it ideal for networks prioritizing IoT scalability and low-latency traffic. The “++=” suffix denotes enhanced licensing with Full Stack Observability (FSO) and premium support.

Key Technical Features
- Port Flexibility: 48x MultiGig RJ45 ports (NBASE-T) + 12x 100G uplinks, supporting mixed-speed environments without hardware swaps.
- Power Efficiency: UPOE++ delivers 90W per port (total 4.32kW), powering PTZ cameras, Wi-Fi 6E APs, and industrial IoT controllers.
- Performance: Built on Cisco’s Silicon One ASIC, enabling non-blocking 3.6 Tbps throughput and MACsec encryption for secure data center interconnects.
- Scalability: Integrates with StackWise Virtual for multi-chassis redundancy and simplified policy management across distributed sites.
――――――――――――
Compatibility and Requirements
This line card operates exclusively in Catalyst 9400 chassis (e.g., C9407R, C9410R) with Cisco IOS-XE 17.12 or later. It requires four 4200W AC power supplies to maximize UPOE++ capacity. Incompatible with non-9400 platforms like the Catalyst 9300 or C9200L.

Primary Use Cases
- Smart City Infrastructure: Powers outdoor IoT nodes (e.g., traffic sensors, smart lighting) with UPOE++ and operational temperature resilience.
- Media & Entertainment: Supports 8K video streaming and real-time rendering farms via 100G uplinks.
- Healthcare Networks: Securely connects medical IoT (e.g., MRI machines, patient monitors) with HIPAA-compliant segmentation.
