Cisco Catalyst IEM-3500-16P Expansion Module

Cisco Catalyst IEM-3500-16P Expansion Module

The Cisco Catalyst IEM-3500-16P Expansion Module adds high-density PoE connectivity to IE3500 base switches for industrial and harsh environments. Providing 16 Gigabit RJ45 PoE/PoE+ downlinks, it delivers reliable line-rate performance in a rugged, fanless IP30 DIN-rail form factor. The module is powered by the host switch (22 W module consumption) and inherits IOS XE features, licensing, and management for seamless integration—making it ideal for powering cameras, sensors, and wireless access points where additional PoE capacity is required.

Key Features:

• 16 × Gigabit Ethernet Downlinks with PoE/PoE+: Expands powered device connectivity; 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.
