The fans wont turn on until you have mining software connected. plug it into your pc and run cgminer. Oh and open it up and make sure all the cables are connected. Some have reported some loose cables particularly the ones in the upper left side of the hashing board.
Thank you for the response. I connected BJ to computer, and run cgminer(3.7.2):
export DISPLAY=:0
export GPU_USE_SYNC_OBJECTS=1
./cgminer -n
cgminer just does not see any USB device.
I understand that the fan connected to the hashing-board could be controlled by cgminer. But there are two case fans(they are directly connected to the power supply) and even the fan inside power supply don't run.
I think here I just don't know how to diagnose if at least the power supply is working.
Can anybody who made your BJ running already tell me please do you see the LED in front panel is on when it's running? Do two case fan fun when turn on the power? Do you need to push the power button in front panel to turn on the machine or just turn on the switch on power supply is enough? Thank you very much!
For cables, I just don't know how many cables should be connected to the board, I can see there are two 6pin PCIE power cables and 1 5pin white power cable, also 1 fan cable, 1 USB cable are connected. I can see the cables from front panel are not connected to any where. Thank you for any help!
