Description

Huawei S5731I-L8T2S2XN: High-Bandwidth 10G Industrial Switch

The Huawei CloudEngine S5731I-L8T2S2XN is a premium industrial-grade Gigabit switch designed for bandwidth-intensive applications in extreme conditions. Unlike standard industrial switches, this model features dual 10G SFP+ uplink ports, providing the high-speed backhaul necessary for modern HD video surveillance and industrial IoT aggregation.

High-Performance Interface Configuration

Downlink Ports: 8 x 10/100/1000Base-T Ethernet ports.
Uplink Ports: 2 x 10G SFP+ ports (Backward compatible with 1G SFP).
Management: 1 x RJ45 Console port for seamless configuration.

Why the S5731I-L8T2S2XN Stands Out?

1. 10GbE Uplink for Future-Proofing

The 10G SFP+ slots allow for massive data throughput, eliminating bottlenecks in networks that handle large-scale data transmission or high-resolution industrial imaging.

2. Industrial-Grade Resilience

Built to survive where others fail. This switch features an IP40-rated metal casing and supports an operating temperature range from -40°C up to +75°C. It is the perfect choice for smart transportation, energy, and manufacturing sectors.

3. Intelligent Reliability (ERPS & iStack)

Supports ERPS (Ethernet Ring Protection Switching) for millisecond-level failover recovery and iStack (Intelligent Stack) technology, allowing you to manage multiple switches as a single logical device.

Power Supply & Modules

To ensure maximum uptime, the S5731I-L8T2S2XN requires robust industrial power modules. We recommend the following:

AC Power: PAC150S12-R (150W AC-to-DC Industrial Module).
DC Power: PDC180S12-AJ (180W DC-to-DC Industrial Module).
10G Transceivers: Compatible with SFP-10G-SR and SFP-10G-LR optical modules.
