Description:
The S5120V3-36F-EI is an enterprise-class Layer 2/Layer 3 Gigabit Ethernet switch independently developed by H3C, belonging to the S5120V3-EI series. It is designed for high-reliability, high-performance and cost-effective network scenarios, ideal for small-to-medium enterprise core layers, large enterprise campus access layers, and branch aggregation layers. Equipped with 8 Gigabit electrical ports, 24 Gigabit SFP ports and 4 1/10GE SFP+ ports, it supports flexible optical-electrical mixed access and high-speed uplink, perfectly adapting to diverse modern enterprise wired network deployment needs.
Based on the mature Comware software platform, it integrates IRF2 intelligent resilient architecture, enabling virtualization of multiple switches into a single logical device for enhanced scalability and reliability. It supports rich redundancy protection, G.8032 ERPS ring protection, QoS mechanisms, and IPv4/IPv6 dual-stack routing to ensure stable operation of critical services. With user-friendly management methods and comprehensive security features, it balances stability, security, and easy maintenance for cost-effective enterprise network construction.
