PXIe Chassis Has Red Flashing LED and Non-Functional Fans

Issue Details

My PXI chassis has a blinking red LED for the fan and the fans are non-functional.


The blinking LED indicates that one or more of the fans is failing and needs to be replaced.

To troubleshoot this issue, replace the cooling fan with a verified functioning cooling fan and test the chassis.

If the cooling fan functions correctly, the original cooling fan is faulty and should be replaced.

If the replacement cooling fan also fails, please contact NI Support.

Additional Information

To purchase a replacement fan, please contact National Instruments.

Alternatively, a replacement cooling Fan Assembly can be ordered from the National Instruments website by following these steps: 

  1. On the National Instruments website, go to the PXIe-XXXX product page.
  2. Click on 'View Product Details'. This will display the family of chassis.
  3. Scroll down to the PXIe -XXXX Chassis and select 'View Accessories'.
  4. Scroll down to Chassis Fan Accessories, where you'll see an option to add a Replacement Fan Assembly.
