Huawei CloudEngine S7703 – Product Documentation

Name: Huawei CloudEngine S7703 - SunSpike
SKU: S7703

Product Overview

The Huawei CloudEngine S7703 is a high-end modular chassis switch from the S7700 series, designed for next-generation enterprise networks. It is a 4U smart routing switch that delivers high-performance Layer 2 to Layer 4 switching services alongside intelligent service optimization capabilities, including MPLS VPN, traffic analysis, comprehensive HQoS policies, controllable multicast, load balancing, and integrated security.

The S7703 chassis features a modular architecture with hot-swappable Main Control Units (MCUs) and Line Processing Units (LPUs), allowing flexible customization for campus core/aggregation or data center deployments. It supports up to 144 × 10GE, 36 × 40GE, or 18 × 100GE ports per chassis, with a switching capacity of 1.92 Tbps and forwarding performance of 1440 Mpps.

Key intelligent features include built-in native Access Controller (AC) capabilities supporting up to 4K APs for wireless convergence, unified user management with multiple authentication methods (PPPoE, 802.1X, MAC, Portal), Super Virtual Fabric 2.0 (SVF 2.0) for network virtualization and simplified management, and iPCA network quality awareness for real-time service flow monitoring.

The S7703 is built on a fully programmable hardware architecture with energy-efficient chips and left-to-rear airflow design. Key components such as main control units, power modules, and fan trays operate in redundancy mode to minimize system downtime. The switch supports advanced features including VXLAN with BGP-EVPN, MACsec encryption, IPv4/IPv6 dual-stack routing, and OpenFlow 1.3.
