# Troubleshooting "Error performing Sequencing\_ProtocolName\_Safestate" error on the NextSeq 1000/2000

Users may encounter the following error during the first cycle of their NextSeq 1000/2000 runs:

"There was an error performing Sequencing\_ProtocolName\_SafeState protocol. Contact Illumina Technical Support"

This error message indicates that the run has terminated and the consumables cannot be re-used. This error typically indicates a communications issue on the instrument that interrupted the run.

**Troubleshooting steps:**

1. Power cycle the instrument; prepare new flow cell while instrument power cycles and reinitializes.
   1. For further information, search for Knowledge Base article **How to power cycle the NextSeq 1000/2000.**
2. Once reinitialized, set up run again with same cartridge and new flow cell.
3. If the instrument fails to initialize properly or the subsequent run fails during clustering, contact [Illumina Technical Support](https://www.illumina.com/company/contact-us.html#/united-states/technical-support) for further troubleshooting guidance.
