Network switch LANBERG ILFE-4P-1GE-1S-90 – unmanaged light industrial PoE, 4 ports (PoE), 1×GigE, 1×SFP, DIN-mount

LANBERG ILFE-4P-1GE-1S-90 is an unmanaged light-industrial Ethernet switch that provides four Power over Ethernet (PoE) ports, one Gigabit Ethernet uplink and one SFP slot in a compact DIN-rail housing. The device delivers basic Layer 2 switching functionality without configuration requirements, combining PoE power and a fiber-capable uplink for small surveillance, access control and industrial network segments where simple, reliable connectivity is required.

Advantages

The switch offers plug-and-play operation with automatic MAC address learning and frame forwarding, reducing installation time and configuration effort. Four PoE-capable ports supply power and data over the same cable to compatible devices such as IP cameras or access points, while the Gigabit uplink provides high-speed connectivity to the core network. The SFP slot enables fiber uplinks for extended reach or electrically isolated connections. A DIN-rail mountable metal enclosure and light-industrial design provide physical robustness suitable for machine rooms, control cabinets and other constrained spaces.

How to use

Install the LANBERG ILFE-4P-1GE-1S-90 on a DIN rail inside a control cabinet or enclosure, connect PoE-enabled devices to the four PoE ports using standard Ethernet cables, and link the Gigabit uplink or SFP fiber module to the upstream network. Power the switch from its power input according to the manufacturer's instructions, ensuring the total PoE power budget matches the connected devices. As an unmanaged device, it requires no software setup; connected devices will obtain link and power automatically where supported.

Recommendations

Place the switch inside a ventilated cabinet away from direct heat sources, verify that the chosen SFP module is compatible with the upstream fiber infrastructure, and calculate the expected PoE power draw before deployment to avoid overloading the switch power budget. Use quality shielded or unshielded Cat5e/Cat6 cables for PoE devices and ensure proper grounding in industrial installations.
