When you're wiring up an industrial networking fieldbus rack, the switch is the piece that ties together controllers, sensors, and HMIs. It has to survive heat, dust, and voltage swings, but it also needs to fit the budget. Two very different approaches stand out: a used Cisco IE-1000-8P2S-LM V03 at $179 and a new PUSR 5/8-port industrial gigabit switch at $27.99. Both target industrial Ethernet switching, but they start from different places.
Quick verdict
If you prefer a plug-and-play, rugged industrial switch for a new installation, choose the PUSR. If you want the Cisco model for an existing setup, the Cisco is the one to consider.

Where each wins
Cisco IE-1000-8P2S-LM V03 is the choice when you want a specific Cisco-model switch and need the included power cable. It is also the pick if you are already running Cisco-style gear and want one more unit to match.
PUSR 5/8 Ports Industrial Gigabit Ethernet Switch is the choice when you want industrial hardening and a simple install. If your project is new and you want to avoid the used-market reset ritual, this is the one.
Product notes
Cisco IE-1000-8P2S-LM V03
The Cisco IE-1000-8P2S-LM V03 is an industrial Ethernet switch with eight ports and a power cable in the box. It is a used unit, so it may show some wear from previous service. It was retired from service without a factory reset, and no passwords are included if one exists. That means you should plan to do a proper reset and put it back into service yourself. The upside is having a Cisco-model 8-port switch ready to wire into your cabinet, with the cable included. The limitation is the used condition and the extra reset step, which makes it a better fit for a buyer who is comfortable with refurbished gear.
PUSR 5/8 Ports 10/100/1000Mbps Industrial Gigabit Ethernet Switch USR-ISG/ISF
For a switch that goes in with minimal fuss, the PUSR series is the opposite of the used Cisco. It is an unmanaged industrial Ethernet switch, which means there are no network management menus to work through. The hardware includes dual power inputs, a fanless body, wide operating temperature from -40°C to 85°C, and IP40 dust protection, so it can sit in a rugged cabinet or on a DIN rail. The compact size makes installation easy in tight spaces. The low listed price makes it an easy choice for budget-constrained projects. The trade-off is that you don't get management features, so traffic tuning, VLANs, and monitoring are off the table.
Final choice by use case
If you're starting fresh and want the least expensive, simplest way to connect field devices, the PUSR is the better fit. It is unmanaged and built for temperature extremes. If you need a Cisco-model switch and don't mind a reset, the IE-1000-8P2S is the one to buy. For most budget-conscious fieldbus installs, the PUSR will do the job without the used-hardware caveats.
