Description:
The S5570S-36F-EI is a high-end enterprise-class enhanced Layer 2/Layer 3 Gigabit Ethernet switch independently developed by H3C, belonging to the S5570S-EI series. It is designed for high-reliability, high-performance core and aggregation layer scenarios, ideal for large enterprise campus backbones, small-to-medium data center access layers, and key branch core networks. Equipped with 24 Gigabit SFP ports, 8 Gigabit Combo ports (electrical/optical optional) and 4 1/10GE SFP+ ports, it supports flexible optical-electrical mixed access and high-speed uplink, perfectly adapting to the high-bandwidth and high-availability needs of modern enterprise core networks.
Based on the advanced Comware V7 software platform, it integrates enhanced IRF2 intelligent resilient architecture, virtualizing multiple physical switches into a single logical device to boost scalability and reliability. This technology supports 2-4 devices for collaborative work and unified management, with long-distance 10GE fiber stacking up to 80KM and millisecond-level link convergence. Adopting pluggable dual power modules (AC/DC optional) and dual fan modules, it achieves 1+1 power redundancy and stable heat dissipation, avoiding core network downtime. Rich QoS, security mechanisms and low-latency forwarding ensure optimal performance, availability and maintainability for enterprise-level core network construction.
