In this document, you will find the instructions on how to update the firmware of your PXI/PXIe chassis, controller, or MXI module.

Note: If you are enabling BitLocker in Windows, updating firmware will activate BitLocker recovery key screen after restarting the PXI controller. Please disable BitLocker or prepare recovery key before updating the firmware.

1. Download the latest firmware image for your PXI/PXIe chassis, controller or MXI module from the NI Software and Driver Downloads website by entering your hardware model. 
2. Save the firmware image to the system that needs to be updated. If the target system runs Real-Time OS, save the firmware image onto the host system.
3. On the host system, use NI Measurement & Automation Explorer (NI MAX) to upgrade the firmware. You must run NI MAX with administrator privileges.
   1. For Windows Systems: Open NI MAX and expand Devices and Interfaces under the My System tab.
   2. For RT systems: Open NI MAX and expand Remote Systems. Right-click the target system and select Web Configuration.
4. Each chassis, controller, or MXI board must be updated separately. For each device to be updated:
   1. Expand the Chassis or Controller tree that will receive the firmware update.
   2. Select the device in the leftmost pane, then click the Update Firmware button in the right pane, sometimes you will need to move the horizontal scroll bar.
   3. Navigate to and select the firmware image file saved in step 1, then click the Open button.
      • A dialog box should open containing information about the firmware image selected.
   4. Confirm the version number displayed is as you expected.
      • If the version is as expected, select the Begin Update button to confirm and start the update.
      • If the version is not as you expected, select the Cancel button and confirm the download in step 1.
5. After a few moments, a dialog box should appear. If the dialog states: The firmware update completed successfully, power cycle the remote controller. The power cycle will require a proper shutdown. After shut down, a disconnect of the AC power from the back of the chassis will be required after the system has successfully shut down properly.
   • If the dialog states that an issue occurred, record the error number/message and contact National Instruments.
