Providing 8 × 1G/100M SFP ports, it delivers reliable line-rate performance in a rugged, fanless IP30 DIN-rail form factor. The module is powered by the host switch (9 W module consumption) and inherits IOS XE features, licensing, and management for seamless integration—ideal for extending fiber access/aggregation where copper is impractical. Key Features: 8 × 1G/100M SFP Ports: 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). Scalable Architecture: Helps expand total system ports up to 19 with compatible IE3500 bases. Technical Overview: Recommended for: Fiber port-density expansion on Cisco IE3500 deployments in industrial/harsh environments. Ports: 8 × 1G/100M SFP. 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 9 W). Show more
