Appendix B: Troubleshooting and Basic Maintenance

Common Faults

The whole machine cannot be powered on: confirm the AC power cord and socket; Check if the INHIBIT switch on the rear panel is set to DEF;

Power blue LED flashing: One power rail voltage exceeds the limit; After unplugging all modules, try again but still contact the dealer abnormally;

Fan green LED flashing: The fan is obstructed by foreign objects or damaged;

Temperature amber LED flashing: Check the ventilation gap between the bottom air inlet and rear air outlet; Confirm the installation of baffles in all available slots; Contact the manufacturer if there is still an alarm despite normal ventilation;

System startup failure: All peripheral modules are unplugged and the fault locating modules are inserted one by one.

Maintenance points

The chassis weighs 8.8 kg and is handled with chassis handles for transportation;

Power off and unplug the AC power cord before maintenance and cleaning; Wipe the shell and focus on cleaning the dust at the air inlet;

Internal maintenance of the chassis must be carried out by authorized engineers;

Built in backup lithium battery, there is a risk of explosion if the wrong model is replaced.
