Buying and selling used industrial Ethernet switches

This category covers used managed and unmanaged industrial Ethernet switches, including copper, fiber and PoE options. Compare port count, RJ45/SFP configuration, port speeds, supply voltage, operating temperature and mounting arrangement. Browse the available product pages below to buy. For the basics, see the difference between an Ethernet switch and a hub.

Network and power compatibility: Verify that the exact model and firmware version support the required VLAN, QoS, multicast management and redundancy features, such as RSTP or MRP. An Ethernet socket alone does not establish compatibility with every network requirement. For PoE models, check the supported standard, power per port, total power budget and suitable power supply. Similar housings or identical port counts do not establish interchangeability.

Access, accessories and testing: For managed devices, establish management access, password/factory-reset status and firmware details. Ask whether SFP modules, power terminal blocks, adapters and DIN rail mounting hardware are included. A lit link indicator does not verify data transmission through every port. Confirm with the selling store which copper/fiber ports, any dual power inputs, management functions and PoE outputs were tested, and under what conditions.

Selling store and item condition: Your seller is the store identified on the product page; confirm price, stock, delivery, specifications and item condition with that store. Used, unused, boxed, repaired, faulty and parts-only items must be clearly distinguished, with known faults and missing accessories disclosed. Test scope, any warranty terms and declarations of conformity with standards are those stated in the selling store's product description. Boxed or unused equipment does not automatically come with a warranty.

Selling an industrial Ethernet switch: Email the brand, complete model code, quantity, working condition or known faults, clear photographs of the equipment and nameplate, and your asking price to otomasyonavm@gmail.com. Identify faulty ports, management-access status and missing accessories. We do not purchase equipment without an invoice. A submission does not constitute a commitment to buy. This section is not a platform where users publish their own listings.

Stock updates: Product listings are updated approximately every 10 days. A sold item may remain listed briefly; confirm availability with the selling store before ordering.
