Error code 200020 after self-test when chassis turns off

Hello

This may seem absurd, but I accidentally ran a self-test to the MAX on one of the NI PXI boards (6533) in my chassis (NI 1042 q) when chassis power was off. He returned with an error code of 200020. The same thing has happened with three other NI PXI boards: 6723 6713 and 6221. I turned on the chassis and the same error code occurred. Then I restarted my computer, responsible for MAX, and no devices were found even more.

I followed the steps here to reset MAX, as well as the devices were recognized again, all the self-tests have passed again.

However, I am concerned as to why it happened. Why the error code keep occurring after that I turned on the chassis? Why MAX ceased to recognize my devices? Something is screwed up when I tried to connect with an off camera? In addition, what does error code 200020? I couldn't find documentation about it anywhere.

Thank you

Hey,.

From your description, it seems that you disable the chassis when the PC is still on. This will cause certainly some problems with your PXI devices, because you're basically hot-swapping PXI devices in your system. This may have also messed up things in MAX, as you saw. You should always have your PXI chassis before your start your computer turned on and turned off after your computer has been shut down. This allows your BIOS correctly enumerate the PXI card, which should hopefully avoid these mistakes in the future.
