Description

Huawei S5751-L8LP2X-RUA: Ultra-Slim 10G Uplink Lite PoE Remote Unit

The Huawei S5751-L8LP2X-RUA is a high-performance, compact Remote Unit (RU) designed for the most demanding environments within Huawei’s Simplified Network Architecture. By combining dual 10G SFP+ uplinks with a Lite PoE (LP) form factor, this device delivers massive data throughput and device power in a slim, fanless casing that fits almost anywhere.

High-Speed & Power Configuration

  • Downlink Ports: 8 x 10/100/1000Base-T Ethernet ports with PoE support.

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

  • Power Capability: Lite PoE support for powering IP phones, sensors, and efficient Wi-Fi APs.

  • Management: Zero-touch deployment via Central Switch.

Key Features of the S5751-L8LP2X-RUA

1. 10G Uplink in a Slim Design

The “X” series uplink provides 10Gbps bandwidth, making this unit perfect for aggregating high-traffic devices without the bulk of a traditional switch. Its slim profile allows it to be hidden in wall boxes, furniture, or narrow ceiling gaps.

2. Lite PoE Efficiency

The Lite PoE (LP) technology is optimized for high-efficiency power delivery. It provides the necessary power for edge devices while maintaining a low thermal footprint, ensuring the unit remains cool even in enclosed spaces.

3. 0dB Silent & Fanless Architecture

Engineered for noise-sensitive areas, the fanless design guarantees silent operation. This makes the S5751-L8LP2X-RUA ideal for high-end executive boardrooms, patient wards, and quiet library study zones.

4. Simplified Management (RU Mode)

Eliminate the need for individual switch management. The S5751-L8LP2X-RUA is treated as a remote interface of the central switch, allowing for centralized configuration, easy upgrades, and rapid plug-and-play installation.

FAQ

FAQ

Q: What is the benefit of the “LP” (Lite PoE) model?

A: The LP model is designed for extreme space efficiency and optimized energy consumption. It is thinner than standard PoE models, making it the best choice for embedded installations.

Q: Does it support 10G SFP+ fiber modules?

A: Yes, the two 10G SFP+ ports support a wide range of optical transceivers and DAC cables for high-speed fiber connectivity up to 10Gbps.

Q: Can this RU work without a central switch?

A: No. As part of the Simplified Network solution, the S5751-L8LP2X-RUA requires a compatible Huawei Central Switch (such as the S6730-H or S5731-H) to function.
