Huawei CloudEngine S7703 PoE – Product Documentation

Product Overview

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

The S7703 PoE 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. Unlike the standard S7703 model where system and PoE power supply slots are independent, all three power supply slots on the S7703-PoE are shared by both the system power supply and PoE power supply, enabling flexible power allocation.

The switch supports up to 144 × 10GE, 36 × 40GE, or 18 × 100GE ports per chassis, with a switching capacity of 4.8 Tbps and forwarding performance of 3600 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 (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 PoE 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.
