Cisco Catalyst IEM-3500-8T Expansion Module
The Cisco Catalyst IEM-3500-8T Expansion Module adds non-PoE Gigabit port density to IE3500 base switches for industrial and harsh environments. Providing 8 × 10/100/1000 RJ45 downlinks, it delivers reliable line-rate performance in a rugged, fanless IP30 DIN-rail form factor. Powered by the host switch (6 W module consumption), it inherits IOS XE features, licensing, and management for seamless integration—ideal where endpoints are externally powered and fiber is not required.
Key Features:
- 8 × Gigabit Ethernet Downlinks (Non-PoE): Cost-efficient copper expansion for sensors, controllers, and gateways.
- 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).
- Right-Sized Expansion: Helps scale total system ports up to 19 with compatible IE3500 bases.
Technical Overview:
- Recommended for: Non-PoE port-density expansion on Cisco IE3500 deployments in industrial/harsh environments.
- Ports: 8 × 10/100/1000 Mbps RJ45 downlinks.
- 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 6 W).
