Huawei CloudEngine S5755-S-HT Series Twins Switch: Product Overview

Name: Huawei CloudEngine S5755-S-HT - Refurbished & Tested - SunSpike
Brand: HUAWEI
SKU: S5755-S-HT

The Huawei CloudEngine S5755-S-HT series is a next-generation, high-reliability Twins switch designed for mission-critical network environments . Built on an innovative “one device, dual-plane” architecture, the series implements full redundancy across management, control, and forwarding planes . This is achieved through a dual-CPU independent management architecture, a dual-engine forwarding design, and support for AC/DC hybrid redundant power supplies .

The core differentiator of the S5755-S-HT series is its ability to build a highly reliable M-LAG network using a single switch . An intelligent switchover module is integrated within the device, allowing single-uplink access terminals to join the M-LAG system. In the event of a master engine failure, traffic is swiftly redirected to the backup engine in sub-second time, ensuring zero service interruption . Software upgrades can also be performed on each engine independently without requiring a device reboot .

This series is specifically tailored for environments with stringent reliability requirements, such as production and manufacturing, smart healthcare, and financial services .
