Deciding between the Cisco IE-3400-8P2S-A and the N-TRON 708TX for an industrial networking fieldbus is really a question of how much you need to spend. One switch is listed at $3,400.00, the other at $159.99. That's a gap of $3,240.01, and it points to two very different buying strategies.
Quick verdict: If you want a tested 8-port industrial switch for a fraction of the higher price, the N-TRON 708TX is the obvious pick. If your network demands the Cisco IE-3400-8P2S-A and you're willing to pay $3,400.00 for a used unit, the Cisco makes sense.
| Product | Brand | Model | Price | Condition |
|---|---|---|---|---|
| Cisco IE-3400-8P2S-A | Cisco | IE-3400-8P2S-A | $3,400.00 | Used |
| N-TRON 708TX | N-Tron | 708TX | $159.99 | New - Open box |
Where each product wins:
Choose the Cisco IE-3400-8P2S-A if your build specifically calls for that exact model or you need a Rugged Series switch from Cisco. The listing shows it was professionally pulled from a working office environment and tested. The catch is the price and used condition.
Choose the N-TRON 708TX if you're outfitting a factory floor without spending thousands. It's an 8-port switch with 10-30VDC input, new open-box condition, and tested working. The catch is that it includes only what's shown in the photos.
Cisco IE-3400-8P2S-A
This is the high-cost route. At $3,400.00, the Cisco is in used condition and the seller says it was tested working after being pulled from a working office environment. It's the specific IE-3400-8P2S-A model, which matters if your network requires that exact switch. The power adapter is not included, and it may show light surface scratches, scuff marks, or edge wear from previous use. That's the trade-off: you're paying a lot more for a tested used unit from a major networking vendor, not for a new product.
N-TRON 708TX
The N-TRON 708TX is the lower-cost pick at $159.99. It's listed as new open-box and was removed from an industrial environment, tested, and working. The title identifies 8 ports and 10-30VDC input, and the attributes list Ethernet/IP communication and a United States origin. No cables, power supplies, or additional accessories are included unless shown in photos. If you want a simple, rugged switch for basic connectivity without the high price tag, this is the one.
Final choice by use case: If you're building a new industrial networking fieldbus link and want to keep startup costs near the floor, the N-TRON 708TX at $159.99 is the practical choice. If you're locked into a Cisco IE-3400-8P2S-A requirement or your team expects that exact model on the rack, the $3,400.00 Cisco is the one to order.
