Huawei Core Switch Components

Huawei core switches are modular devices composed of Main Processing Units (MPUs), Line Processing Units (LPUs), Fabric Units (SFUs), power modules, and fan modules, all designed with redundancy for high reliability.

Key Components

Main Processing Units (MPUs): The MPU is the central control module responsible for managing the switch's operations, routing protocols, and system intelligence. Huawei core switches, such as the S12700H and S16700 series, use redundant MPUs to ensure carrier-grade reliability and uninterrupted service in case of module failure. Line Processing Units (LPUs): LPUs handle the data forwarding and interface connectivity.

They provide ultra-high-density access ports, including GE, 10GE, 25GE, 40GE, 100GE, 200GE, and 400GE, depending on the model.

LP

Us are modular, allowing flexible expansion and adaptation to network growth. Fabric Units (SFUs): SFUs form the internal switching fabric, connecting MPUs and LPUs to provide high-speed data transfer across the switch. They enhance system bandwidth and support smooth network evolution, ensuring that the switch can handle large-scale traffic efficiently.

Power Modules: Huawei core switches use modular power supplies with redundancy (1: 1 or N+1 configurations) to maintain continuous operation even if one module fails. This design supports high availability in enterprise and data center environments. Fan Modules: Cooling is critical for high-performance switches.

Redundant fan modules ensure proper airflow and thermal management, preventing overheating and maintaining stable operation under heavy workloads. Programmable Chips: Huawei core switches are equipped with fully programmable forwarding chips, allowing user-defined forwarding processes. This enables flexible service rollout without replacing hardware, protecting customer investments and supporting rapid deployment of new services.

Additional Features

Redundancy and Reliability: All key components (MPUs, LPUs, SFUs, power, and fans) are designed with redundancy to provide carrier-grade reliability.

High-

Density Ports: Core switches support a wide range of port types and densities, suitable for aggregation and core layers in enterprise and data center networks. Security and Management: Features include secure data access, MACsec, terminal identification, and support for advanced authentication methods. Scalability: Modular design allows easy expansion and compatibility with existing network cards, ensuring investment protection.

Huawei core switches, such as the CloudEngine S12700H, S16700, and CE12800 series, combine these components to deliver high-performance, scalable, and reliable solutions for enterprise campuses and data centers.
