The refurbished Cisco IE-3100-8T2C-E is a rugged, compact industrial Ethernet switch from the Catalyst IE3100 Series, built for demanding environments like manufacturing, energy, transportation, and smart cities. This manageable switch features a total of 10 Gigabit Ethernet ports, including 8 fixed 10/100/1000 Base-T RJ-45 copper downlink ports and 2 Gigabit combo uplink ports. The combo uplinks offer flexible connectivity, supporting either copper or SFP fiber connections (SFP modules sold separately) to integrate seamlessly with various network infrastructures. Its fanless, DIN-rail-mountable form factor is designed to withstand harsh industrial conditions, including an extremely wide operating temperature range of $-40^\circ\text{C}$ to $75^\circ\text{C}$ and resistance to shock and vibration.

Running on the Cisco IOS XE operating system, the IE-3100-8T2C-E provides built-in security features such as Secure Boot and the Cisco Trust Anchor module, ensuring a secure network foundation. It supports essential industrial automation protocols like EtherNet/IP and Modbus, making it a versatile component for connecting devices like sensors, cameras, and PLCs. For network resiliency and high availability, the switch incorporates features such as the Resilient Ethernet Protocol (REP) and Media Redundancy Protocol (MRP), alongside dual-input DC power capability. The refurbished model offers a cost-effective solution to deploy high-speed, secure, and reliable Gigabit Ethernet connectivity in space-constrained or harsh industrial settings while supporting Layer 2 switching capabilities for efficient traffic management.
