Cisco Catalyst IE3400 8 GE Copper Expansion Module | Industrial Ethernet — CON-L1NCO-IEM3408T

Add more wired capacity where industrial networks need it most with the Cisco Catalyst IE3400 8 GE copper expansion module. Built for Catalyst IE3400 environments, it extends copper-based Gigabit connectivity for devices that depend on direct Ethernet attachment at the edge. This module is a strong fit for industrial deployments where control systems, sensors, and distributed equipment require additional ports without redesigning the network. By keeping connectivity in the Catalyst IE3400 family, IT and OT teams can preserve platform consistency while expanding access where cabinet space and network segmentation are tightly managed. For organizations standardizing industrial Ethernet infrastructure, an expansion module like this can be more valuable than a lower-cost standalone switch. It preserves the operational model of the parent platform, supports cleaner deployment planning, and helps maintain a consistent management approach across ruggedized edge environments.
