Cisco IW9165E-F-AP: How Does This Ruggedized
Military-Grade Ruggedization for Extreme Environm...
Core Specifications and Design Purpose
The Cisco C9400-LC-12QC= is a high-density line card designed for the Catalyst 9400 Series modular switches, targeting data center and enterprise core deployments. It provides 12x 40G/100G QSFP28 ports in a single slot, enabling non-blocking throughput of up to 1.2 Tbps. Built for scalability, it supports Cisco Crosswork Network Automation and Multi-Domain Insights for traffic visibility across hybrid clouds.
Q: Does it support breakout configurations for lower-speed devices?
A: Yes. Each QSFP28 port can be split into 4x 10G or 4x 25G connections via breakout cables, making it adaptable for legacy infrastructure while maintaining future-ready capacity.
Use Cases and Deployment Advantages
Q: Is this line card suitable for hyperscale data centers?
A: Absolutely. The C9400-LC-12QC= excels in environments requiring high port density and ultra-low latency, such as AI/ML workloads, high-frequency trading platforms, or media rendering farms. Its deep buffers (up to 12 MB per port) prevent packet loss during traffic bursts.
Q: How does it integrate with Cisco’s security framework?
A: Leveraging Cisco Tetration Analytics, the line card provides application-level encryption monitoring and microsegmentation. For compliance-heavy industries like healthcare or finance, this ensures adherence to data sovereignty regulations.
