Issue Details

This document covers several troubleshooting tips associated with National Instruments MXI-3 and MXI-4 hardware.
  1. The computer does not boot or I receive a Blue Screen.
  2. MXI-3/4 Interface or PXI boards are not detected by the Operating System or Resource Conflict is Present.
  3. MXI-3/4 is not detected in the system.

Solution

The computer does not boot or I receive a Blue Screen.

  1. Remove all PXI devices from the chassis. 
  2. Make sure the MXI boards are securely seated and placed into the proper slots. The MXI card must be in the first slot of the secondary chassis. (If the first chassis has a controller in it, the PXI MXI can be in any other slot)
  3. If you are using Windows XP, upgrade to the most current service pack for your operating system.
  4. Make sure the ends of the cables are fully inserted into the connectors on the MXI boards. The link light on the MXI should stay on the continuously while the system is powered up. If the LED flashes at anytime the link has been lost, possibly due to a loose connection. 
  5. Try changing PCI slots in the computer.
 

MXI-3/4 Interface or PXI boards are not detected by the Operating System (OS) or Resource Conflict is Present.

  1. Windows OS: Verify that the MXI is being detected by the Operating System. Run the MXI-3 optimization software. A pop-up box will report if the MXI board is not detected. If the MXI is not detected, then locate the troubleshooting steps for the MXI board not being detected.
  2. If the boards in the PXI chassis are not showing up in MAX do a Refresh (F5).
  3. Make sure the chassis are being powered up in the proper sequence. Power the PXI chassis and then the computer. When daisy-chaining MXI controllers, power on the chassis starting with the chassis at the end of the chain and move towards the host controller.
  4. Make sure the ends of the cables are fully inserted into the connectors on the MXI boards. The link light on the MXI should stay on the continuously while the system is powered up. If the LED flashes at anytime the link has been lost, possibly due to a loose connection. 
  5. If the boards in the PXI chassis are still not showing up, check the Device Manager. Delete any Unknown Devices with yellow question marks next to them, and Scan for Hardware Changes or Refresh the Device Manager.
  6. If a device can be seen in Device Manager but is not being detected by the driver or is not working, refer to the documentation for that device. It may be helpful to remove working devices during troubleshooting.
  7. If all the hardware exists except for one or two devices, then it may be an issue with those particular devices. At that point it may be easier to troubleshoot those devices by removing the properly working devices and then doing more testing. 
  8. If none of the hardware in the secondary chassis is detected, but the MXI is detected, then contact National Instruments Technical Support.
 

MXI-3/4 is not detected in the system.

  1. Remove all PXI devices from the chassis. They can be reinstalled later.
  2. Make sure the chassis are being powered up in the proper sequence. Power the PXI chassis and then the computer. When daisy-chaining MXI controllers, power on the chassis starting with the chassis at the end of the chain and move towards the host controller. 
  3. Make sure the ends of the cables are fully inserted into the connectors on the MXI boards. The link light on the MXI should stay on the continuously while the system is powered up. If the LED flashes at anytime the link has been lost, possibly due to a loose connection. You may also want to ensure there is no damage to the cable, especially the fiber cable. If there is still a problem with the link, then contact National Instruments Technical Support.
  4. Verify that the Plug and Play service is enabled in the computer's operating system. On Windows 2000 and XP machines, this option can be found in the Services application which is available under Administrative Tools in the Control Panel. Scroll down in the list of services until you find Plug and Play and make sure that it is Started with a Startup Type of Automatic.
  5. If the MXI is still not being detected it may be that the BIOS is causing the problem. Some BIOS have a selection to specify if the operating system is plug and play. In some cases this can cause a problem. If the BIOS of the computer has a selection for Plug and Play OS, then set this option to NO even if you are using a Plug and Play operating system. If this does not help, then set it back to YES when you are done troubleshooting the system. At that time, ensure that setting it back to YES does not affect the system.
  6. If the MXI is still not detected, then contact National Instruments Technical Support.
