Issue Details

My PXI chassis appears in NI Measurement & Automation Explorer (MAX) with a red X next to it, but the cards in the chassis appear correctly. What does a red X mean and how can I connect to my chassis?


Delete the chassis in NI MAX, reboot the chassis, and re-identify it in MAX.

If the red X persists, turn off the computer and empty the all of the cards from the chassis while keeping the controller seated. When you reconnect to the empty chassis, it should appear correctly in MAX. Add the cards one by one back to the chassis.
