How to Power Cycle the NovaSeq X Series Instruments

Background

Restarting or power cycling the NovaSeq X Series instruments can resolve many common communication or instrumentation issues. However, these actions should only be performed when recommended by Illumina Tech Support or Field Service. Power cycling the instrument is expected to take up to 45 minutes.

If the NovaSeq X Series Control Software is not accessible or not responding, do not shutdown through the Linux Operating System (OS). Contact Illumina Tech Support for further guidance.
