Huawei S5751-L8P2X-RUA: High-Bandwidth 10G Uplink PoE+ Remote Unit

The Huawei S5751-L8P2X-RUA is the flagship Remote Unit (RU) for Huawei’s High-Quality Simplified Network Architecture. It is specifically engineered for environments that demand both high-power delivery (PoE+) and ultra-high bandwidth (10G Uplink). By bringing 10GbE fiber connectivity and power directly to the edge, it enables a truly future-proof network.

Premium Interface & Power Specs

  • PoE+ Downlink Ports: 8 x 10/100/1000Base-T Ethernet ports (Supports 802.3at/af).

  • 10G Uplink Ports: 2 x 10G SFP+ slots (Eliminates congestion for high-density traffic).

  • PoE Budget: Flexible budget from 124W to 240W (depending on power input), perfect for Wi-Fi 6 APs and PTZ cameras.

Key Advantages of the S5751-L8P2X-RUA

1. 10G Uplink: No More Bottlenecks

With the rise of Wi-Fi 6/7 and 4K video streaming, standard 1G uplinks are easily saturated. The dual 10G SFP+ uplinks on the S5751-L8P2X-RUA ensure that all connected PoE devices can transmit data at full speed without latency.

2. Advanced PoE+ Power Supply

Supporting up to 30W per port, this RU can easily power high-performance devices like smart lighting controllers, biometric terminals, and high-end VoIP phones, reducing the need for local electrical outlets.

3. Simplified Architecture (Zero Configuration)

Forget complex independent management. This RU acts as an extended interface of the central switch. It is plug-and-play, automatically inheriting all security policies and configurations from the core switch (e.g., CloudEngine S6730-H).

4. Silent, Fanless Reliability

Despite its high performance, the unit remains fanless and silent (0dB). It’s the perfect fit for “hidden” installations in ceilings, wall boxes, or directly inside high-end office spaces.

FAQ

FAQ

Q: Does the S5751-L8P2X-RUA require a separate power adapter?

A: Yes, as a Remote Unit, it typically requires an external DC power adapter. The PoE budget (124W or higher) depends on the capacity of the power supply used.

Q: Can I use this RU with 1G SFP modules?

A: Yes, the 10G SFP+ ports are backward compatible with 1G SFP modules, offering flexibility if you haven’t upgraded your core to 10G yet.

Q: How is this model different from the S5751-L8T2X-RUA?

A: The “P” in S5751-L8P2X-RUA stands for PoE. This model can provide power to connected devices, whereas the “T” model (L8T2X) only provides data connectivity.
