Providing 16 Gigabit RJ45 downlinks, it delivers reliable line-rate performance in a rugged, fanless IP30 DIN-rail form factor. The module is powered by the host switch (11 W module consumption) and inherits IOS XE features, licensing, and management for seamless, unified operation—ideal for scaling device connectivity where endpoints are externally powered. Key Features: 16 × Gigabit Ethernet Downlinks (Non-PoE): Cost-efficient port expansion for sensors, controllers, and gateways that don’t require inline power. Ruggedized, Fanless Design (IP30): Built for space-constrained industrial sites with DIN-rail mounting. Seamless System Integration: Inherits Cisco IOS XE features and licensing from the base IE3500 switch. Simple Operations: Managed (Cisco IOS XE WebUI/CLI; optional Cisco Catalyst Center). Scalable Architecture: Helps expand total system ports up to 27 with compatible IE3500 bases. Technical Overview: Recommended for: Port-density expansion on Cisco IE3500 deployments in industrial/harsh environments. Ports: 16 × 10/100/1000 Mbps RJ45 downlinks (non-PoE). PoE Budget: No PoE. Switching Capacity: — Forwarding Rate: Line-rate on all ports (all packet sizes). Management: Managed (Cisco IOS XE WebUI/CLI; optional Cisco Catalyst Center). Security: Inherits features and license tier from the base IE3500 switch. Energy Efficiency: Fanless operation; powered by base switch (module consumption 11 W).
