ON-8528-4XF / ON-8528-4XFL
The Optech Network Solutions ON-8528-4XF / ON-8528-4XFL is an industrial-grade modular managed Ethernet switch designed for mission-critical industrial, utility, power-substation, renewable-energy, and other demanding OT networking applications. The platform provides three modular Ethernet interface slots and four 10G SFP+ uplink ports, supporting flexible copper and fiber network configurations. It combines high-capacity Gigabit switching with advanced network management, redundancy, security, precision time synchronization, and industrial networking functions. The series is available in two software/functionality variants: ON-8528-4XF — Layer 3 Managed Version ON-8528-4XFL — Layer 2 Managed Version Both models use the same modular hardware platform, while Layer 3 routing capabilities are available on the ON-8528-4XF version. The supplied source identifies the original variants in the same product family.
