Issue Details

I have a PXIe chassis with an remote controller, MXI-Express (MXIe), connection to my computer. Everything is connected, but I can't see my devices in NI MAX. 
  • I have my MXIe card in slot 1 of my PXIe chassis, and the power LED on my MXIe card is either off or flickering red
  • I have a PXIe chassis with a built-in MXIe controller, and the activity LED on my chassis is solid red
How do I fix this problem?

Solution

Ensure the PXI chassis and computer are connected properly and powered.

PXIe with MXIe Card
  • If the PWR LED on the card is off, then there is no power being supplied to the device
  • If the PWR LED on the card is red, then the power supplied is out of specification
  • If the LINK LED on the card is off, then there is no link to the chassis
PXIe with Integrated MXIe
  • If the LED on the chassis is off, then there is no power being supplied to the device
  • If the LED on the chassis is blinking red, then the power supplied is out of specification
  • If the LED on the chassis is solid amber, then there is no link to the chassis
If your LED status indicates that there is no link to the chassis, it is posible that the MXIe connector was inserted upside down. To correct this, power off your PC, and PXI chassis, and rotate the connections on both ends of the cable to ensure they match.


 If this doesn't resolve your issue and you still are not able to see your device in NI MAX, refer to the MXI Compatibility and Connectivity Troubleshooting Guide for further troubleshooting steps.
