Cisco Industrial Ethernet IE 4000 Switches - Refurbished, Used, New

The Cisco Industrial Ethernet 4000 series delivers rugged, gigabit-capable switching designed for the most demanding operational environments. Built for use in manufacturing, transportation, energy, and smart city infrastructure, these switches combine hardened enclosures, extended temperature support, and resistance to vibration and electrical noise to ensure consistent uptime.

Available in compact DIN-rail form factors, the IE 4000 provides flexible connectivity with multiple Gigabit Ethernet ports and uplink options. Select models include PoE+ support with power budgets up to 240 W, enabling deployment of IP cameras, wireless access points, and industrial sensors without additional power infrastructure.

Reliability is central to the IE 4000 design. Features such as Ethernet Ring Protection (REP), Media Redundancy Protocol (MRP), and Parallel Redundancy Protocol (PRP) allow for sub-second recovery during link failures, ensuring continuity for mission-critical applications. Zero-touch replacement and SwapDrive support streamline field maintenance and minimize downtime.

At NetworkTigers, both refurbished and used Cisco Industrial Ethernet 4000 switches are available. Refurbished units undergo rigorous testing and verification to ensure they meet performance standards. Used units are confirmed ready for production networks. Inventory is kept in stock, orders ship quickly, and every purchase includes a 365-day warranty, ensuring long-term peace of mind and value.
