PXI-5105 has been in continuous use and was operating without issue until recently, when the -239021 error code was seen. The code is also reported when self-test is executed on the PXI-5105 via NI-MAX. Running under Windows 7 OS, and control of PXI chassis via MXI-express link to remote PC.
Looking for guidance on any troubleshooting, resets, or other activities that can be tried before pursuing an RMA. Are there things that can be tried to restore normal operation for this failure code?
