Description
Cisco SX550X-12F-K9-NA 12-Port 10G SFP+ Layer 3 Stackable Managed Switch | 240 Gbps
The Cisco SX550X-12F-K9-NA is a high-performance enterprise-class pure 10 Gigabit fiber stackable managed switch designed for core, aggregation, and high-speed data center or enterprise backbone deployments. As part of the Cisco 550X Series SX550X platform, it delivers ultra-fast Layer 2 and Layer 3 switching intelligence, advanced routing capabilities, and true stacking functionality for scalable network architectures.
Built with a 10G SFP+ fiber-first architecture, this switch is optimized for high-bandwidth uplinks, server aggregation, and inter-switch backbone connectivity. It provides 240 Gbps non-blocking switching capacity and 178.56 Mpps forwarding performance, ensuring wire-speed traffic handling for demanding enterprise workloads.
With true hardware stacking support, multiple units can operate as a single logical system with unified management, high availability, and failover protection. The SX550X-12F also supports advanced security, QoS, IPv6 routing, VLAN segmentation, and enterprise-grade network controls, making it ideal for mission-critical backbone infrastructure.
This model is PoE-free by design, focusing entirely on high-speed fiber switching efficiency and maximum throughput performance in a compact 1RU form factor.
