When you're equipping an industrial networking fieldbus, the switch you pick has to balance reliability, environment tolerance, and cost. Two very different options sit at opposite ends of the spectrum: the Cisco IE-3400-8P2S-A Rugged Series and the Phoenix Contact FL SWITCH 1085255. One is a used unit from a working office; the other is a brand-new switch aimed at automation networks. With a price gap of more than $3,200, your decision likely comes down to whether you need the Cisco's Rugged Series positioning or the Phoenix Contact's new, low-cost approach.
Quick Verdict
If you want a switch that has already been proven in an office environment and you're comfortable with a used unit that shows some wear, the Cisco IE-3400 is the stronger candidate. If you prefer a new device at a much lower price and your network is focused on basic industrial Ethernet communication, the Phoenix Contact FL SWITCH is the way to go.

Where the Cisco Wins
The Cisco IE-3400 is a Rugged Series switch, a line built for demanding environments. The used unit was professionally pulled from a working office and tested to be working, so it has a track record. While it may show light surface scratches and edge wear, the price reflects its status as a Rugged Series product. If you're specifically looking for a Rugged Series switch and you're willing to invest in that positioning, the Cisco is the one.
Where the Phoenix Contact Wins
The Phoenix Contact FL SWITCH is new in box, giving you peace of mind that you're the first owner. Its design is centered on reliable data communication in industrial control networks, manufacturing plants, and process automation, making it a natural fit for PLCs, HMIs, and other automation components. The price is dramatically lower than the Cisco, so you can equip a larger network without straining your budget. For straightforward Ethernet switching in an automation context, this is a strong pick.
Product Notes
Cisco IE-3400-8P2S-A Rugged Series Industrial Ethernet Switch

The Cisco's Rugged Series branding signals that it was built for demanding conditions, and as a used unit from a working office, it has a known operational history. It's been tested to be working, but the power adapter is not included, so you'll need to supply that. Expect light scratches, scuffs, and edge wear from previous use-cosmetically imperfect but still operational. If you're building a network where a failure could be costly, the Cisco's rugged positioning helps justify the investment. The higher price also buys you the promise of a specific product line.
Phoenix Contact FL SWITCH 1085255

This switch arrives new in box, so you're the first owner. It's designed for reliable performance in industrial automation, with integration into PLCs, HMIs, and machine-to-machine communication setups. That makes it a natural fit for a control cabinet or factory floor. The main limitation is that its stated purpose is automation environments, so if you're networking a traditional office, it might not be the intended use case. It doesn't carry the "Rugged Series" label that the Cisco does, but its design still emphasizes ruggedness for continuous industrial operation. For basic Ethernet switching, it gets the job done.
Final Choice by Use Case
Choose the Cisco IE-3400 if you need a switch with rugged industrial design and you can live with a used unit, wear and all, and your budget can stretch to its price point. Choose the Phoenix Contact FL SWITCH if you want a new, straightforward industrial switch for automation networks and you're watching costs-it delivers essential Ethernet switching without the higher price tag.
