Cisco Catalyst IEM-3500-6T2S Expansion Module

The Cisco Catalyst IEM-3500-6T2S Expansion Module adds a balanced mix of copper and fiber connectivity to IE3500 base switches for industrial and harsh environments. Providing 6 Gigabit RJ45 downlinks and 2 fixed 1G/100M SFP uplinks, it delivers reliable line-rate performance in a rugged, fanless IP30 DIN-rail form factor. The module is powered by the host switch (10 W module consumption and inherits IOS XE features, licensing, and management for seamless integration—ideal for right-sizing access where a compact copper/fiber combination is required.

Key Features:

• 6 × Gigabit Ethernet Downlinks (Non-PoE: Cost-efficient port expansion for endpoints that don’t require inline power.
• 2 × 1G/100M SFP Uplinks: Flexible fiber connectivity for resilient aggregation/backbone links.
• Ruggedized, Fanless Design (IP30: Built for space-constrained industrial sites with DIN-rail mounting.
• Inherits IOS XE Features & Licensing: Operates as part of the IE3500 system for consistent L2/L3 capabilities.
• Easy Management: Managed (Cisco IOS XE WebUI/CLI; optional Cisco Catalyst Center.
