CloudEngine S5755-S-HT Series Twins Switch
The CloudEngine S5755-S-HT series Twins switches are Huawei's new-generation high-reliability switches.Adopting a multi-switch redundant architecture, this series features a single device with dual planes design, supporting redundant backup for both the management plane and forwarding plane. The AC/DC hybrid power supply solution further ensures system-level highly reliable operation.A core highlight of the product is that for access devices connected through a single network port, a single device can independently build a highly reliable network. Built-in intelligent switching modules enable sub-second forwarding link switching in case of component failures or software and hardware exceptions, ensuring non-stop services. During software upgrades, management network elements can switch automatically and rapidly, allowing upgrade completion without device restart.Tailored for scenarios with stringent network reliability requirements, this series is widely applied in key sectors such as manufacturing, smart healthcare and financial services, providing a stable and intelligent network foundation for enterprise digital transformation.
Control Reliability
Key components of the control system adopt dual redundancy, with sub-second switching upon single-point faults to ensure uninterrupted device management and control
UForwarding Reliability
Adopting a full redundancy architecture for forwarding links, it achieves sub-second convergence upon link or component faults to ensure continuous and stable data forwarding
Upgrade Reliability
Supports independent in-service upgrade of dual engines, requiring no downtime throughout the process and achieving service non-perception
