Description
The Cisco N9K-C9508-B3-E is a high-capacity modular switch chassis designed for enterprise and cloud-scale data center environments. Built on the Cisco Nexus 9500 Series architecture, this 8-slot chassis delivers exceptional scalability, high availability, and operational efficiency for core and aggregation network deployments.
This bundled configuration includes one Supervisor Engine B (SupB), three power supplies, two system controllers, four enhanced fabric modules (FM-E), and three fan modules. Together, these components provide resilient power, optimized fabric throughput, and front-to-back airflow for consistent thermal performance.
With support for N+N and N+1 power redundancy, high-density line card expansion, and advanced management interfaces, the N9K-C9508-B3-E is ideal for organizations building flexible, future-ready data center infrastructures that demand reliability, performance, and simplified operations.
