The Advantech EKI-8528-4XF and EKI-8528-4XFL series represents a power-plant-grade 19-inch rackmount modular managed Ethernet switch engineered for mission-critical industrial networks requiring the highest levels of reliability and security. This versatile platform supports up to 24 Gigabit Ethernet ports through three modular 8-port slots, complemented by 4x10G SFP+ uplink ports, delivering an impressive 128 Gbps switching capacity and 95 Mpps forwarding rate. The Layer 3 variant (EKI-8528-4XF) incorporates advanced routing capabilities including OSPF v2/v3, VRRP v2, RIP v1/v2, PIM-SM, and NAT with support for up to 3K IPv4 and 1.5K IPv6 routing entries, enabling seamless data exchange across large industrial infrastructures. Built specifically for harsh power utility environments, the switch features heavy industrial-grade hardware with superior EMC resistance against extreme electrical noise and temperature fluctuations, operating reliably from -40 to 85°C. Security is paramount in modern OT environments, and the EKI-8528 series delivers comprehensive protection through full IEC 62443-4-2 cybersecurity certification, 802.1X authentication, RADIUS/TACACS+ support, and extensive ACL capabilities. For power substation applications, the switch is IEC 61850-3 Edition 2 and IEEE 1613 certified, supporting GOOSE QoS, SMV QoS, C37.238 power profiles, and MMS protocols. Time-sensitive networking capabilities include IEEE 802.1AS, 802.1Qbv, 802.1Qbu, 802.1CB, and IEEE 1588v2 PTP with boundary and transparent clock modes. Network resilience is ensured through IEC 62439-3 compliant PRP and HSR protocols, X-Ring Pro with sub-20ms recovery, and comprehensive spanning tree support. The modular design accommodates flexible Ethernet configurations via RJ45 or SFP modules, while dual power module slots support both high voltage 110/220 VAC/VDC and low voltage 24/48 VDC inputs with overcurrent and reverse polarity protection. Ideal for power substations, renewable energy installations, and mission-critical data centers. Available from Recab, your Nordic partner for Advantech industrial networking solutions.
