Maintenance Points

• Regular Inspection: Check whether the fan of the power supply board (if any) is running normally and whether there is dust accumulation on the heat sink.
• Monitoring and Alarm: If a power supply abnormality alarm occurs in the monitoring system, first check the input and output voltage of this board.
• Replacement Suggestion: During system upgrade or major maintenance, it is recommended to use the original PWA86739-01U for replacement to ensure compatibility and protection level.
