E-link Debuts LNK-AIMC208GMP90: 90W PoE++ Solar Voltage Booster AI Smart Managed Industrial Ethernet Switch

Introducing the LNK-AIMC208GMP90 — A World-First Solar Voltage Booster PoE++ Switch

E-link is proud to unveil the LNK-AIMC208GMP90, a world-first Mini Industrial AI Smart Managed PoE++ Ethernet Switch that integrates a self-developed intelligent management system with a built-in voltage boost circuit specially optimized for solar power supply applications. By blending the strengths of managed and unmanaged switches, this compact device delivers enterprise-grade visibility and control in a rugged, DIN-rail form factor.

An Intelligent, App & Web Managed Experience

Engineers can monitor device status through multiple methods — a mobile APP (Android), a PC web management interface, and an on-board LED display — without any additional test tools. The one-click LED screen presents a real-time dashboard covering voltage, current, internal temperature, Ethernet and SFP port link speeds, SFP transmit/receive optical power, and detailed DDM diagnostics such as optical power, wavelength, transmission distance, link rate, and module temperature.

• Rich APP & Web Management: Intuitive graphical dashboard for full device status, complete SFP information and DDM diagnostic data, customizable optical power alarm thresholds, and user-defined scheduled port/device reboots.
• Smart Managed Functions: Fiber port alarm, scheduled system reset, scheduled PoE restart, and one-click VLAN isolation.
• Redundant-Mode Auto-Recovery: If the destination port of a packet is link-down, it forwards the packet to the other port of the backup pair.

Wide 9–54VDC Input with Built-In Voltage Booster

Optimized for solar and battery-fed deployments, the built-in booster circuit converts a wide DC input range into a stable 48V PoE output, scaling available power according to the input voltage.

The switch complies with the IEEE 802.3af/at/bt PoE++ PSE standard and is available in customizable versions for Starlink Gen 2 / Gen 3 compatibility.

PoE Standards & Port Configuration

Each unit is equipped with 4×10/100/1000Base-T RJ45 PoE++ ports and 4×10/100/1000Base-T RJ45 PoE+ ports, plus 2×100/1000/2.5GBASE-X SFP fiber uplink ports. Ports 1/3/5/7 support IEEE 802.3af/at 30W, while ports 2/4/6/8 support IEEE 802.3af/at/bt 90W. The device offers a 30Gbps non-blocking switching capacity with a 1 Mbit packet buffer and 9K jumbo frame support.

Rugged Industrial Reliability

Housed in a compact aluminum case measuring only 98 × 67 × 64 mm and weighing 400g, the switch meets IP40 protection and operates reliably in harsh industrial temperatures from −40°C to +75°C. Wide 6KV lightning surge protection on all ports, dual redundant power supplies, and an MTBF exceeding 200,000 hours keep Ethernet running stably 24×7. DIN-rail mounting is included by default.

Application Scenarios

• Intelligent Manufacturing & Automation: data transmission and multi-device interconnection.
• Power & New Energy: surveillance communication and cluster networking.
• Rail Transit & Tunnel Engineering: real-time video monitoring and signal transmission.
• Oil, Gas & Mining Sites: stable communication in demanding environments.
• Smart City & New Infrastructure Deployment.

The unit also serves autonomous driving, humanoid robots, AI computing, metallurgy, chemical engineering, outdoor research base stations, and field weather monitoring.

Regulatory Approvals

The LNK-AIMC208GMP90 complies with ISO9001, CE, FCC Part 15 Class A, and RoHS, and is tested to EN55022, EN55024, and IEC 61000-4-2/3/4/5/6/8 standards for ESD, RS, EFT, surge, CS, and PFMF immunity. The standard model is the LNK-AIMC208GMP90-SFP; SFP modules, power supplies, and mounting options are available as separate options.
