Huawei S12708 Core Switch Parameters

The Huawei S12708 is a high-performance, modular core switch with up to 8 line processing units (LPUs), 4 switch fabric units (SFUs), and support for extensive L2/L3 services, SDN, and high-availability clustering.

Hardware Overview

The S12708 is part of the Huawei S12700 series and is designed for next-generation campus and core networks. It features a modular chassis supporting up to 8 LPUs and 4 SFUs, providing high scalability and redundancy. The chassis supports installation in N66E or N68E cabinets, with a maximum voltage range of 90–290 V AC and frequency of 47–63 Hz.

The switch uses a Huawei Ethernet Network Processor (ENP) for high-speed packet processing.
