Cisco Catalyst IEM-3500-16T Expansion Module

The Cisco Catalyst IEM-3500-16T Expansion Module adds high-density non-PoE Gigabit access to IE3500 base switches for industrial and harsh environments. 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).
