Description

Huawei S5751-L8T2HX-RUA: High-Performance 10G Uplink Remote Unit

The Huawei S5751-L8T2HX-RUA is a flagship non-PoE Remote Unit (RU) engineered for Huawei’s High-Quality Simplified Network Architecture. Equipped with an enhanced “HX” high-bandwidth pipeline featuring dual 10G SFP+ uplinks, this unit is designed to aggregate massive data streams from desktops, servers, or high-speed terminals directly to the core network with zero latency.

High-Speed Interface Configuration

  • Downlink Ports: 8 x 10/100/1000Base-T Ethernet ports (Non-PoE, line-rate forwarding).

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

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

Key Advantages of the S5751-L8T2HX-RUA

1. Enhanced “HX” 10G Future-Proof Bandwidth

Standard Gigabit RUs can bottleneck when multiple workstations transfer large files simultaneously. The S5751-L8T2HX-RUA features dual 10G SFP+ ports, delivering 20 Gbps of uplink potential. This makes it ideal for media editing studios, financial trading desks, and high-tech research labs.

2. Plug-and-Play Architecture (Zero O&M)

Say goodbye to complex edge-switch configurations. This Remote Unit acts as a remote line card for your central switch. It requires zero local configuration; simply connect the fiber uplink, and it automatically retrieves its profile, status, and security policies from the central core.

3. 0dB Fanless Silent Design

Built with advanced natural heat dissipation, the unit has no mechanical fans. It operates in complete 0dB silence, making it perfect for executive boardrooms, open-plan office spaces, school classrooms, or library desks.

4. Green Energy Efficiency

By simplifying the hardware components and optimizing the chip architecture, the S5751-L8T2HX-RUA consumes significantly less power than traditional standalone switches, lowering your enterprise TCO (Total Cost of Ownership).

FAQ

FAQ

Q: What does the “HX” stand for in the model name?

A: The “HX” denotes that this model belongs to the enhanced performance tier, featuring 10G SFP+ ultra-high-speed uplinks for high-density data backhaul, differentiating it from standard 1G uplink RUs.

Q: Does the S5751-L8T2HX-RUA support Power over Ethernet (PoE)?

A: No, this is a non-PoE model (“T” version). It is designed strictly for data transmission for devices that have their own power supplies (like PCs, smart TVs, or network printers). If you need PoE, please check our listing for the S5751-L8P2X-RUA.

Q: Can I use 1G SFP optical modules in the 10G ports?

A: Yes, the 10G SFP+ uplink ports are backward compatible with standard 1G SFP modules, allowing you to deploy the hardware now and easily upgrade to 10G when your network core expands.
