6. Installation and Maintenance
Installation Position
It must be installed in the designated chassis position (left position) and adjacent to the system monitor to maintain the logic of power distribution.
Wiring Requirements
Use a dedicated Power Input Cable and ensure the connection is tight and reliable to prevent power supply interruption caused by loosening.
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.
