Before you begin, make sure you have properly followed the installation instructions for your hardware.
Because MXI-Express connectivity issues can surface through many different symptoms, only the most common symptoms reported are covered in this guide. If you encounter an issue that is not covered by any of the existing information, please reach out to NI Support.
This guide is not meant for troubleshooting intermittent MXI-Express issues, remote control systems using PXIe-8301, or PXI systems with embedded controllers.
This guide is organized by common MXI-Express related symptoms. Identify which situation best fits the behavior you are experiencing and follow the corresponding troubleshooting steps in the order that they are provided. It is important that you follow every step completely and carefully. If you experience more than one behavior covered in this guide, follow the guide in the order that it is presented.Check the Hardware Model Specific Information section for further troubleshooting steps and considerations for your specific device model.
If your computer encounters boot issues without MXI-Express hardware, contact the computer manufacturer to get it back into a bootable state, or replace with a functional computer.
Note: The MXI-Express BIOS Compatibility Software uses patented technology to take control from the BIOS in enumerating PXI(e) systems and handle enumeration on its own. This compensates for BIOS’s that cannot handle enumerating large complex PCI(e) architectures such as those introduced by PXI(e) systems.
Note: Motherboard manufacturers will fix bugs in BIOS versions that cause PCI(e) enumeration to fail and crash. By ensuring that you are running the latest BIOS version, you reduce the probability that the behavior is caused by a bug in the BIOS.
If you do not experience this behavior, refer to Symptom 3: Computer/Device Manager cannot detect, recognize, or connect to my PCI/PCIe MXI card.
If the PXI Platform Services version is not compatible,
Refer to Error 10 in Windows Device Manager for MXI Connection.
Refer to Error 12 with MXI-Express (MXIe).
Refer to Code 31 in Windows Device Manager While Using a MXI Connection.
Other errors that occur in Device Manager are not MXI-Express hardware specific. If you experience an error that is not one of the above, try searching for it in the support knowledgebase.
Refer to PXI/PXIe MXI-Express Card LED Red or Amber.
This table contains important troubleshooting information and considerations when using certain MXI-Express hardware. Please review this section for further troubleshooting steps for your specific model.
There are different variations of the PCIe-8361. The PCIe-8361 (195315x-01L) does not have dip switches. This means that the MXI-Express BIOS Compatibility Software is not supported for this module.
Both PCI-Express and PXI-Express devices will show up in MAX.
If you are using a x8 MXI-Express fiber cable, there is a switch on the PCIe-8381 and PCIe-8382 that needs to be set. If you are using copper cables, this is set by default.
Fiber cables have a Host and Target orientation. Make sure each cable end is plugged into the correct piece of hardware.
If you are running the MXI-Express BIOS Compatibility Software, you must also run the NI MXI Configuration utility that installs with it. This utility flips the software switch instead of flipping a hardware DIP switch.
The software switch is persistent, so you only need to run the utility once.
If you move the PCIe-8398, PXIe-8398, or PXIe-8399 to a different computer, the new computer will need to run the MXI-Express BIOS Compatibility Software, or you will have to rerun the NI MXI Configuration utility to disable the software switch.
If the software switch is enabled, and the computer does not have MXI Compatibility installed, the MXI-Express hardware will appear incorrectly as a “NI Boot Time PCI Resource” in MAX.
Make sure the ends of the cables are fully inserted and properly oriented into the connectors on the MXI-Express boards.
MXI-Express devices are heavily dependent upon the individual motherboard manufacturers and will sometimes run into connectivity issues. Complex MXI-Express configurations may pose a challenge for the BIOS of some systems to correctly enumerate all the resources necessary, which may cause the system to freeze during the boot process.
Please contact NI Support if you have any questions on these troubleshooting steps or MXI-Express products.
