Issue Details

My PXI controller recently went offline during a power surge and now it will not boot past the BIOS.  What can I try to get it working again? 

My PXI controller has started booting straight to the BIOS instead of to the OS 


Try the following to isolate whether it is a software or hardware issue: 
  • Inspect the controller for bent pins in the backplane, burn marks, or other physical damage.  If any of these are present, the controller may have had a hardware failure and will have to be repaired through RMA. 
  • Remove modules from your chassis and attempt to boot again.  If the boot works, the modules in your chassis may be drawing too much power and the power supply may need to be repaired. 
  • Replace the CMOS battery.  For detailed instructions on how to do this, consult the manual for your controller.
  • Try reinstalling the operating system using a bootable USB drive.  Further instructions can be found in the Related Links. 
  • For RT controllers, ensure that the network settings of the controller have not changed.  If possible, connect a monitor to the controller and see if it boots far enough to acquire an IP address.  See Cannot Connect to PXI Real-Time Target on a Network for more detailed instructions. 
  • Check if there are any USB devices plugged into the controller. If there are, then remove these and try booting again without them.
If none of these steps get you past the BIOS or there is visible damage on the controller, it may need to be sent in for repair.
