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).
