Fault Diagnosis Matrix (Examples)

SymptomPossible CauseDiagnostic ActionRequired EquipmentRepair LevelOperational RiskEscalation 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.
