Example Fleet Scenario
| Symptom | Possible Cause | Diagnostic Action | Required Equipment | Repair Level | Operational Risk | Escalation Path |
|---|---|---|---|---|---|---|
| Low / Zero Hashrate | Hashboard chip failure | Scan hashboard and check chain errors | Hashboard tester and infrared camera | Board Level | ● High | RMA / Board Replacement |
| Frequent Reboots | PSU instability | Check voltage rails, ripple and connectors | Multimeter and oscilloscope | Component Level | ● Medium | PSU Replacement |
| High Chip Temp | Poor thermal contact or airflow | IR scan, fan test and heatsink seating check | IR camera and anemometer | System Level | ● Medium | Thermal Service |
| Network Dropouts | Control board or cable fault | Check logs, replace cables and test port | Network tester | Component Level | ● Low | Board Replacement |
| Fan Alarm | Fan failure or obstruction | Inspect fans, bearings and replace as needed | Tachometer | Component Level | ● Low | Fan Replacement |
Matrix is not exhaustive. Always follow manufacturer troubleshooting and safety guidelines.
