Quick verdict
For an industrial networking fieldbus cabinet, the switch choice often comes down to a money question: $3,400 for a Cisco IE-3400-8P2S-A or $39.99 for an Industrial Ethernet Switch. That works out to roughly a $3,360 spread, so the real question is what you are buying with that difference. The higher-priced unit is a Cisco IE-3400-8P2S-A; the lower-priced unit is a compact industrial Ethernet switch. Both belong in industrial networking fieldbus installations, but they are not interchangeable. Here is how to choose.
Head-to-head at a glance
| Decision point | Cisco IE-3400-8P2S-A | Industrial 10P Ethernet Switch |
|---|---|---|
| Listed price | USD 3,400.00 | USD 39.99 |
| Condition | Used | New |
| Type | IE-3400 Rugged Series industrial Ethernet switch | 10-port industrial Ethernet switch |
| Port layout | IE-3400-8P2S-A model | 8 gigabit RJ-45 + 2 SFP |
| Industrial specs | Rugged Series | IP40, 6KV lightning resistance, -40°C to 85°C |
Where each product wins
The Cisco IE-3400-8P2S-A wins when your plan actually calls for Cisco's IE-3400 Rugged Series hardware. If the asset list says that model, the other switch can't fill the same role.
The Industrial 10P Ethernet Switch wins when you don't have a fixed Cisco requirement and you want the practical benefits of the compact industrial switch. It leaves more room elsewhere in the build.
Product notes
Cisco IE-3400-8P2S-A Rugged Series Industrial Ethernet Switch

This used Cisco unit was professionally pulled from a working office environment and tested to be working, which makes it a direct match if your industrial networking fieldbus design specifies the IE-3400 model. The main reason to choose it is that specific Cisco model identity. The limitations are the used condition, possible light surface scratches and edge wear, and the fact that no power adapter is included. If you go with this switch, plan to supply your own adapter and accept that it may show signs of previous ownership.
Industrial 10P Ethernet Switch w/Industrial DIN-Rail 2 SFP Port 20Gbps Capacity

The Industrial 10P is a new, compact 10-port switch with 8 gigabit RJ-45 ports and 2 SFP slots, plus DIN-rail and wall mounting. It is a managed switch with a 20Gbps switching capacity, and it includes industrial protections such as IP40, 6KV lightning resistance, and a -40°C to 85°C operating range. The reason to choose it is that you get a managed 10-port switch with mounting flexibility in a new unit. The limitation is the port ceiling: you have exactly 8 copper ports and 2 SFP slots, so larger layouts will need an additional switch.
Final choice by use case
Choose the Cisco IE-3400-8P2S-A if you need to match that Cisco IE-3400 model and are prepared to supply your own power adapter.
Choose the Industrial 10P Ethernet Switch if you want a managed switch and do not need to match a named Cisco model.
