Huawei CloudEngine S7712 – Product Documentation

Name: Huawei CloudEngine S7712 - SunSpike
SKU: S7712

Product Overview

The Huawei CloudEngine S7712 is a high-density modular chassis switch within the CloudEngine S7700 series, designed for large-scale enterprise campus networks, data centers, and metropolitan area networks. The S7712 chassis offers 14 total slots, comprising 2 main control unit (MPU) slots and 12 line processing unit (LPU) slots, making it the highest-capacity model in the S7700 series.

The switch features a modular architecture with dual MPU redundancy, hot-swappable power supplies and fan modules, and support for Power over Ethernet (PoE++). It delivers high-density 10GE, 40GE, and 100GE connectivity, with a maximum port density of up to 576×10GE, 144×40GE, or 72×100GE ports per chassis.

Key capabilities include VXLAN with BGP-EVPN for virtual network fabrics, MACsec hop-by-hop encryption for enhanced security, CSS (Cluster Switch System) hardware clustering, and native wireless access controller (AC) functionality supporting wired and wireless convergence. The switch is powered by Huawei’s programmable Ethernet Network Processor (ENP) chips, enabling flexible service provisioning and support for MPLS VPN, H-QoS, hardware-assisted traffic analysis, and fast fault detection (BFD/HSR).

With its robust switching capacity, extensive port density, and advanced features such as iPCA (Packet Conservation Algorithm for Internet) quality awareness and unified user management, the CloudEngine S7712 is ideally suited for campus core/aggregation layers, serving as a central aggregation point for multiple S7706 or S7703 devices.
