Huawei S5751-L8P2HX-RUA: The Ultimate 10G Uplink PoE+ Remote Unit

The Huawei S5751-L8P2HX-RUA is the flagship Remote Unit (RU) within the High-Quality Simplified Network Architecture. Designed for environments that cannot compromise on speed or power, this unit integrates 8 Gigabit PoE+ ports with dual 10G SFP+ uplinks. It represents the pinnacle of “Fiber-to-the-Room” (FTTR) technology, delivering massive backhaul capacity and high-wattage power to the network edge.

Flagship Interface & Power Delivery

  • Downlink Ports: 8 x 10/100/1000Base-T Ethernet ports (PoE+ supported).

  • Uplink Ports: 2 x 10G SFP+ slots (Ultra-high-speed 10 Gigabit backhaul).

  • PoE Budget: Flexible budget from 124W up to 240W (depending on external power module), supporting IEEE 802.3at/af standards.

  • Architecture: Centrally managed “Central Switch + RU” architecture.

Why the S5751-L8P2HX-RUA is the Best-in-Class Choice

1. Enhanced “HX” Performance Pipeline

The “HX” designation signifies an enhanced hardware architecture. This unit is built to handle heavy concurrent traffic—such as multiple 4K streams or high-speed Wi-Fi 6/7 backhaul—ensuring that the CPU and switching fabric maintain ultra-low latency even under full load.

2. Future-Proof 10G Fiber Uplinks

With dual 10G SFP+ ports, you are no longer limited by Gigabit bottlenecks. This RU provides the high-speed fiber path necessary for the next generation of enterprise applications, ensuring your investment remains relevant for years to come.

3. High-Wattage PoE+ Support

With up to 30W per port, this unit effortlessly powers high-demand devices:

  • Next-Gen Wi-Fi 6/7 Access Points

  • High-Resolution PTZ Security Cameras

  • Interactive Smart Displays

  • Biometric Access Control Systems

4. 0dB Fanless & Silent Operation

Despite its powerful “HX” performance, the unit remains completely fanless. The silent 0dB operation makes it ideal for executive offices, high-end hotel suites, and quiet healthcare environments.

Compatible Central Switches

To unlock the full potential of the S5751-L8P2HX-RUA, pair it with Huawei’s high-performance central switches:

  • CloudEngine S6730-H Series

  • CloudEngine S5731-H Series

  • CloudEngine S12700E Series
