Cisco Catalyst IE-3505-8P3S-A Switch
The Cisco Catalyst IE-3505-8P3S-A Switch is a rugged, scalable industrial Ethernet platform built for harsh OT edge environments. It features 8 Gigabit RJ45 downlinks with PoE/PoE+ and 3 fixed 1G/100M SFP uplinks, delivering reliable line-rate performance in a compact, fanless IP30 DIN-rail form factor. With a 240 W base PoE budget—expandable to 480 W via an optional module—it powers cameras, sensors, and access points. Running Cisco IOS XE with the Network Advantage license, it supports advanced Layer 2/Layer 3 capabilities, modular expansion via IEM modules (up to 27 ports, and integrates with Cisco Catalyst Center for streamlined operations.
Key Features:
-
8 × Gigabit Ethernet PoE/PoE+ Ports: Power and data for industrial endpoints, 240 W base PoE (expandable to 480 W with an optional module.
-
3 × 1G/100M SFP Uplinks: Flexible fiber uplinks for reliable aggregation/backbone connectivity.
-
Ruggedized, Fanless Design (IP30, −40°C to +75°C: Reliable operation in harsh, space-constrained sites with DIN-rail mounting.
-
Layer 2 & Layer 3 with Network Advantage: Advanced routing/segmentation features for OT/IT convergence (license-dependent.
-
Easy Management: Managed (Cisco IOS XE WebUI/CLI; optional Cisco Catalyst Center.
