Issue Details


I have an NI MXI-Express x1, x4, x8, or x16 for PXI Express remote controller. What power-up options are available for the downstream system?

Solution

The PXIe MXI Express x1/x4/x8/x16 board can automatically power-on downstream PXIe chassis when the host PC is turned on, or power-on the host PC when the chassis power is turned on.  

You can use the attached program to configure your MXI Express system for upstream/downstream power-up functionality. This functionality is supported on the following controllers: 
  • PXIe-8360
  • PXIe-8370
  • PXIe-8381
  • PXIe-8388
  • PXIe-8389
  • PXIe-1073 chassis with integrated controller. 
This program will not work for :
  • Chassis with integrated MXI controllers, such as the PXI-1033 
  • Setups using fiber optic MXI Express cables.  
Note: This program is written in LabVIEW 2012, and requires the LabVIEW 2012 Runtime Engine and NI-VISA

To utilize the attached program, follow the steps outlined below:
  1. Download and run the NIPXIRemoteConfig.exe attachment
  2. Verify that your remote controller is identified under the Controller Model heading
  3. Use the check boxes under the Settings heading to specify either a Downstream power-on configuration (PXIe chassis powers-on when host PC powers-on) or an Upstream power-onconfiguration (host PC powers-on when PXIe chassis powers-on)
        5. Restart your system and verify the desired functionality

Additional Information

On older models, this functionality was disabled by default to ensure that downstream chassis are powered up before the host. If after enabling this functionality your system does not work properly, you may need to disable these features. Some NI PXI Express chassis have an "inhibit mode switch" as an alternative to remotely power-on the chassis. You can use this functionality to force the power sequence of the MXI-Express controller.
