Troubleshooting and maintenance

Common Faults

The whole machine is not powered on: confirm the power cord and socket; Confirm that the INHIBIT switch on the rear panel is in DEF position;

Power blue LED flashing: One power supply voltage exceeds the limit; Dismantle all modules and retry; Continuously contact the manufacturer for the malfunction;

Fan green LED flashing: foreign objects blocking the fan or hardware failure of the fan;

Temperature amber LED flashing: Check the ventilation of the air inlet and outlet, and confirm that all empty slots are equipped with baffles; Contact the service provider 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 weight of the chassis is 11   kg. When handling, use the chassis handle and be careful not to injure it;

Before maintenance and cleaning, turn off the power and unplug the AC power cord; Wipe the shell and focus on cleaning the dust at the air inlet;

The device is only used indoors and has a maximum working altitude of 2000 meters.

Safety instructions

Before disassembling or plugging modules, the AC power supply must be completely disconnected;

Prohibit blocking ventilation holes; Stay away from liquid, high humidity and high temperature environments;
