UCSC-GPU-A100-80= Accelerator: Architectural
Hardware Architecture & NVIDIA-Cisco Co-Engineering...
Core Functionality and Target Applications
The C9400-LC-48HX= is a high-performance line card designed for Cisco’s Catalyst 9400 Series modular switches, delivering 48x 10G/25G Multi-Gigabit Ethernet ports and 12x 40G/100G uplinks. Built for data-intensive environments, it supports hyperscale campus cores, AI/ML data lakes, and high-frequency trading networks where low latency and high throughput are non-negotiable.
Key Technical Specifications
- Port Configuration: 48x 10G/25G SFP28 downlinks + 12x 40G/100G QSFP28 uplinks (breakout capable to 48x25G).
- Throughput: 1.44 Tbps per slot with support for Cisco StackWise-480, enabling seamless stacking of up to 8 chassis.
- Advanced Features: Integrated with Cisco DNA Center for intent-based automation and Cisco Cyber Vision for IoT/OT security.
This line card is tailored for enterprises consolidating legacy 1G/10G infrastructure into unified 25G/100G backbones.
Addressing Critical User Concerns
Q: What supervisor engines are required for full functionality?
A: The C9400-LC-48HX= requires C9400-SUP-1XL or newer supervisors. Older modules (e.g., SUP-1) lack the packet buffer capacity to handle its 25G traffic at scale.
Q: How does it handle power redundancy?
A: Pair with dual C9400-PWR-6KAC power supplies for N+N redundancy. Each line card draws up to 600W under full load.
Performance Comparison with Competing Line Cards
- C9400-LC-24XS: Offers 24x25G ports but lacks the 48HX’s 12x100G uplinks, limiting spine-layer scalability.
- C9400-LC-48T: Provides 48x1G/10G ports but cannot support 25G or modern AI-driven traffic patterns.
The LC-48HX= stands out for hyperscale uplink density and multi-speed flexibility, making it ideal for enterprises prioritizing long-term agility.
Sourcing and Deployment Best Practices
For guaranteed compatibility and lifecycle support, purchase the [“C9400-LC-48HX=” link to (https://itmall.sale/product-category/cisco/). Ensure your chassis runs IOS XE 17.9.1 or later to leverage features like predictive network analytics and MACsec encryption.
Final Perspective
The C9400-LC-48HX= isn’t just a hardware upgrade—it’s a strategic enabler for enterprises navigating the collision of IoT, AI, and hyperscale data. While its upfront cost may deter some, the operational savings from consolidating disparate networks into a single 25G/100G fabric are undeniable. Having deployed this card in telecom edge deployments, I’ve seen it transform latency-sensitive applications from bottlenecks into differentiators. In an era where data velocity defines competitiveness, this line card is less an option and more a mandate.
