Define what is being delivered
Specify model, quantity, accessories, power supply, controller and stated condition in the order. Agree which serial numbers are included and how a mismatch will be handled. Ask whether repairs, board replacements or firmware changes are known. Record the agreed test method and acceptance criteria before shipment, so both parties evaluate the same evidence.
Inspect before energizing
Photograph the packaging, labels, connectors and visible condition as received. Look for transport damage, corrosion, loose components or signs of liquid exposure. Manufacturer precautions call for inspecting a new machine too; a used machine deserves the same care. Do not energize equipment showing electrical damage or loose internal parts until the responsible technician has assessed it.
Match identity across the evidence
Match the physical serial number with the dashboard and test record where the model exposes it. Save the exact firmware and controller information. A seller’s hashrate screenshot proves little if it cannot be tied to the delivered unit and timestamp. Ask for a continuous, identifiable test record rather than several attractive screenshots from unknown machines.
Test under an agreed operating condition
Use suitable power and cooling and record the operating mode. Check board detection, repeated alarms, local output, accepted pool work and measured power together. Compare against the agreed specification and tolerance for that unit. A short test can reveal obvious faults but cannot prove remaining service life; keep those two conclusions separate.
| Record | Why it matters |
|---|---|
| Serial + test time | Connect results to the delivered unit |
| Firmware + mode | Explain performance conditions |
| Pool + local output | Check productive work beyond startup |
| Power + alarms | Reveal instability and abnormal operation |
Close with a signed result and recovery details
Save passed checks, unresolved issues, photographs and the agreed remedy in one record. Reconfigure administrative access and pool destinations under the new owner’s control. Keep shipping and purchase evidence with the serial list. If a fault appears later, a dated baseline is more useful than trying to reconstruct the original condition from memory.
