# Troubleshooting Focus Camera (FTM) system check failure on the NovaSeq 6000

A Focus Camera failure during the NovaSeq 6000 system checks can be caused by a transient instrument communication issue, or it can be indicative of an instrument hardware issue.

**Troubleshooting steps:**

* Perform a power cycle on the instrument.
  * For more information on power cycling, search for Knowledge Base article **How to Power Cycle the NovaSeq 6000 System?**
  * **Note**: Focus Camera test on system check will fail if it is performed immediately after a run failure. Power cycling the instrument is **required** to reset communication pathways.
* Repeat the system check after the power cycle. For additional details, search for Knowledge Base article **How to perform system checks on the NovaSeq 6000?**
* Contact [Illumina Technical Support](https://www.illumina.com/company/contact-us.html) if the Focus Camera test fails after the power cycle.
