Cisco Catalyst IE-3500-8U3X-E Switch

The Cisco Catalyst IE-3500-8U3X-E Switch is a rugged, high-power industrial Ethernet platform built for harsh OT edge environments. It features 8 Gigabit RJ45 downlinks with PoE/PoE+/4PPoE and 3 high-speed 10G/1G SFP+ uplinks for scalable aggregation, delivering reliable line-rate performance in a compact, fanless IP30 DIN-rail form factor. With a 480 W PoE budget, it powers demanding endpoints such as PTZ cameras, wireless access points, and industrial sensors. Running Cisco IOS XE with the Network Essentials license, it provides foundational Layer 2/Layer 3 capabilities, supports modular expansion via IEM modules (up to 27 ports), and integrates with Cisco Catalyst Center for streamlined operations.

Key Features:

• 8 × Gigabit Ethernet Downlinks with PoE/PoE+/4PPoE: Delivers up to 480 W total PoE budget to power high-draw industrial devices.
• 3 × 10G/1G SFP+ Uplinks: High-speed fiber uplinks for resilient backbone and aggregation connectivity.
• Ruggedized, Fanless Design (IP30, −40°C to +75°C): Reliable operation in harsh industrial conditions with DIN-rail mounting.
• Layer 2 & Layer 3 with Network Essentials: Foundational routing/segmentation features suited for OT/IT convergence (license-dependent).
• Easy Management: Managed (Cisco IOS XE WebUI/CLI; optional Cisco Catalyst Center).

Technical Overview:
