my pxie-1072 chassis would not power on after ac cable plugged.
the chassis was attached with pxie-8135,pxie-5122,pxie-5422,and a third-party module
i tried to figure which unkown device in win10 is that third-party module, so i power off win10,unplug ac cable,unplug 5122 and 5422,leaving only controller and the third-party module on chassis,and then plug ac cable,power on win10,install diver for the third party card.during the progress,i noticed that fan produce louder noise.after the driver installed,i power off win10,unplug ac cable, and plug 5122&5422 back.
then i found after i pluged ac cable back, the led lights on the chassis power buttom and 8135 led indicator no longer on.
what should i do to troubleshoot?what could probably caused this condition?
