E-link LNK-AIMC204GMP90: 4-Port 90W PoE++ AI Smart Managed Industrial Switch with Solar Voltage Booster

E-link Releases the LNK-AIMC204GMP90: A 4-Port 90W PoE++ AI Smart Managed Industrial Switch with Built-In Solar Voltage Booster

E-link has launched the LNK-AIMC204GMP90, a compact industrial PoE switch that combines four 90W PoE++ copper ports, two 2.5G SFP fiber uplinks and a built-in voltage boost circuit designed specifically for solar and low-voltage DC sites. The unit is an independently developed E-link design and, according to the company, the first device of its class to merge managed-switch intelligence with unmanaged-switch simplicity.

Hardware: 4 x 90W PoE++ In, 2 x 2.5G Fiber Out

Each switch provides four 10/100/1000Base-T RJ45 ports delivering IEEE 802.3af/at/bt PoE++ up to 90 watts per port (bt Type 4), plus two 100/1000/2.5GBASE-X SFP slots for fiber uplink over multimode, single-mode or long-haul links up to 200 km. Switching is store-and-forward with a 20 Gbps non-blocking capacity, 9K jumbo frame support and a 1 Mbit packet buffer.

• 4 x 10/100/1000Base-T PoE++ — af 15.4W / at 30W / bt Type 3 60W / bt Type 4 90W, End-span and Mid-span, Mode A and Mode B
• 2 x 100/1000/2.5GBASE-X SFP — backward compatible with 100BASE-X and 1000BASE-X optics, 2.5G enabled by DIP switch
• 6KV surge protection on all ports, aluminium IP40 housing, DIN-rail mount, 98 x 67 x 46 mm and only 400 g
• Dual redundant DC inputs on a 4-pin terminal block for 24/7 operation

Voltage Booster: Full PoE Output From 9–54V DC Inputs

The built-in boost stage converts whatever DC rail is available on site into a stable 48V or 56V PoE output, so integrators no longer need a separate 54V power supply. That matters on solar, battery and vehicle installations where nominal voltages are 12V or 24V rather than 48V.

Custom versions are available for Starlink Gen 2 and Gen 3 compatibility, allowing a single switch to power satellite terminals alongside CCTV or wireless equipment on the same mast.

AI Smart Management With a One-Click LED Dashboard

E-link's self-developed intelligent management system is accessible from an Android app and a PC web UI, and also from an on-board LED screen that cycles through live system data with a single button press. Engineers get dashboards for system current, voltage and internal temperature, per-port PoE status, PSE active pairs, supply voltage and power consumption, plus full SFP DDM diagnostics including TX/RX optical power, wavelength, module temperature and link rate.

• Fiber port alarm with user-defined optical power thresholds and red LED indication
• Scheduled system reset and PoE scheduled restart per port or device-wide
• One-click VLAN isolation for fast port segmentation without a CLI
• Redundant ring mode with automatic recovery if a destination port goes link-down

Built for Harsh and Remote Environments

The switch operates from -40°C to +75°C, tolerates 5–95% non-condensing humidity, and carries an MTBF rating above 200,000 hours. Regulatory approvals include CE, FCC Part 15 Class A, RoHS and ISO9001, with EMC and EMS testing to EN55022, EN55024 and IEC 61000-4-2/3/4/5/6/8.

Ordering and Availability

The shipping model is LNK-AIMC204GMP90-SFP, supplied with a DIN-rail bracket as standard. A 240W/5A 48VDC power supply (open-wire terminal block) and SFP transceivers are available separately. E-link supports OEM and ODM programmes, including custom firmware labelling and Starlink-specific PoE variants; contact the E-link sales team with the model number for datasheets, samples and lead times.
