Cisco Catalyst IEM-3500-4MU Expansion Module
The Cisco Catalyst IEM-3500-4MU Expansion Module adds multi-gigabit PoE capability to IE3500 base switches for industrial and harsh environments. Providing 4 × 100M/1G/2.5G RJ45 downlinks with PoE/PoE+/4PPoE, it delivers reliable line-rate performance in a rugged, fanless IP30 DIN-rail form factor. The module is powered by the host switch (20 W module consumption) and inherits IOS XE features, licensing, and management for seamless integration—ideal for powering high-draw endpoints like PTZ cameras and next-gen access points while adding 2.5G bandwidth.
Key Features:
- 4 × 100M/1G/2.5G RJ45 with PoE/PoE+/4PPoE: Multi-gig PoE expansion for high-bandwidth, high-power devices; PoE budget supplied by the base switch.
- 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.
