Issue Details

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


The cooling fan LED blinking indicates that one or more of the fans are failing and needing a replacement.

To troubleshot this issue. Replace the cooling fan with a known 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.
