The Advantech EKI-2428G-4CI is a rugged unmanaged Ethernet switch built for high-bandwidth industrial networks. It features 24x Gigabit copper ports and 4x RJ45/SFP combo ports, offering a total switching capacity of 56 Gbps to support fast, reliable data transmission across edge-to-core industrial environments.
Designed for applications requiring large-scale connectivity and fibre flexibility, the EKI-2428G-4CI supports both copper and fibre uplinks, with SFP slots enabling transmission distances up to 110 km (depending on SFP module). Auto-negotiation, MDI/MDIX, and full/half-duplex operation make deployment simple, while an 8K MAC address table ensures stable performance in busy networks.
Engineered for harsh conditions, this switch is housed in a robust IP30-rated metal enclosure and offers extended wide-temperature support from -40°C to +70°C. Compliance with EMC, EMI, shock, vibration, and freefall standards ensures dependable operation in demanding environments such as transportation, utilities, process control, and factory automation. Dual DC power inputs (12–48 VDC) with reverse polarity and overload protection further increase system reliability, while dual relay outputs provide immediate alerts for power faults.
With its combination of rackmount form factor, redundant protections, and industrial-grade resilience, the EKI-2428G-4CI is the ideal unmanaged solution for scaling industrial Ethernet backbones where long-distance fibre and rugged design are essential.
