Huawei CloudEngine S5751-L8T2J-RUA Product Documentation

Name: Huawei CloudEngine S5751-L8T2J-RUA - Refurbished & Tested - SunSpike
Brand: HUAWEI
SKU: S5751-L8T2J-RUA

Product Overview

The Huawei CloudEngine S5751-L8T2J-RUA is a 10GE uplink remote unit switch designed as part of Huawei’s innovative streamlined campus network architecture. Based on Huawei’s proprietary “Asteroid” lean architecture, this switch simplifies the traditional three-layer network model (access, aggregation, core) into a two-layer architecture with only access and core layers, significantly reducing network deployment and management complexity .

This remote unit functions as a port expansion module for central switches such as the Huawei S6700/S5700 series, enabling flexible port scaling without complex reconfiguration . The S5751-L8T2J-RUA provides GE data access capabilities and supports multiple deployment scenarios including enterprise offices, educational institutions, hotels, and healthcare facilities .

The device features a fanless design with natural heat dissipation, achieving ultra-low power consumption with an average maximum power consumption of less than 1W per port, delivering approximately 30% energy savings compared to traditional switches . Supporting both desk and wall-mounting options, this switch offers flexible installation to meet various site requirements .
