Cisco IEM-3300-8T= Catalyst IE3300 8-Port GE Copper | Expansion Module — IEM-3300-8T=

Expand wired access at the industrial edge with the Cisco Catalyst IE3300 8-port GE copper expansion module. The IEM-3300-8T= adds eight Gigabit Ethernet copper ports to a compatible IE3300 platform, giving teams a clean way to increase port density without replacing the switch. That matters in plants, utility sites, and distributed facilities where the network must grow in place and remain easy to manage. This module is designed for environments that value predictable connectivity and platform consistency. Instead of introducing a separate access layer or forcing a larger redesign, it extends the existing IE3300 footprint with additional copper interfaces for endpoints, controllers, and local devices. For procurement teams, that means a more controlled path to expansion. For operations teams, it means fewer moving parts and a familiar Cisco architecture. The result is practical scale at the edge: more ports, the same platform, and less disruption. When the requirement is to connect more devices while preserving the installed switching standard, this expansion module delivers a focused and cost-conscious answer. Ideal For Adding more wired endpoints to an industrial IE3300 switch deployment Expanding port count in a plant-floor or utility edge network Supporting controllers, sensors, and local devices on copper connections Increasing access capacity while keeping the existing Cisco switching platform Why This Product 1 8 copper ports versus smaller expansion options 2 Gigabit Ethernet access versus mixed-speed add-ons 3 IE3300 integration versus standalone access switches 4 Compact expansion versus full switch replacement
