Issue Details

I have an NI MXI-Express x1, x4, x8, or x16 in my PC for PXI Express remote controller. What power-up options are available for my PXI Express Chassis?


PXI Express chassis have power that can be controlled by the PXI Express system controller. The PXIe MXI Express x1/x4/x8/x16 board can use this functionality to automatically power-on downstream PXIe chassis when the host PC is turned on, or even 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. 

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-on configuration (host PC powers-on when PXIe chassis powers-on)
  4. Restart your system and verify the desired functionality

Note: The attached program is written in LabVIEW 2012, and requires the LabVIEW 2012 Runtime Engine and NI-VISA. This program only needs to be run once per PXI/MXI configuration.

Additional Information

The upstream/downstream power-up functionality is supported on the following controllers: 
PXIe-8360, PXIe-8370, PXIe-8381, PXIe-8388, and PXIe-8389, as well as the PXIe-1073 chassis with integrated controller. This program will not work for chassis like the PXI-1033 (the functionality is hardwired in these devices). Additionally, due to the differences in power requirements between copper and fiber optic MXI Express systems, setups using fiber optic MXI Express cables will not support this power-up option.  

Note: On older models, the upstream/downstream power-up 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. Ensure the the "inhibit mode switch" is set to the off position to allow the controller slot to turn on the chassis.
