Huawei S9300 series (S9300 for short) terabit routing switches are high-end smart switches tailored for multiservice networks. The S9300 uses Huawei's intelligent multilayer switching concept to provide high-performance L2/L3 switching services as well as rich network applications such as High-Definition (HD) video, elastic cloud computing, hardware IPv6, unified security, and H-QoS. Secure, reliable, and scalable, and providing converged, end-to-end routing and switching functions, the S9300 switches are widely used in Wide Area Networks (WANs), Metropolitan Area Networks (MANs), and data centers to help carriers build application-centric networks.

The S9300 is available in three models: S9303, S9306, and S9312. All S9300 models use interchangeable modules and components for inexpensive switching capacity and port expansion. In addition, S9300 models use innovative energy saving technologies that greatly reduce energy consumption and noise without compromising performance or stability.
