# Introducing the Illumina NovaSeq X System
**Background**
Coinciding with the v1.3 NovaSeq X Control Software release, Illumina is launching the NovaSeq X Sequencing System, a single-sided version of the NovaSeq X Series platform.
**Important Notes for the NovaSeq X Sequencing System:**
* The instrument can sequence all available NovaSeq X Series Kit configurations.
* The instrument will be single-sided and will only allow sequencing on Side A of the instrument.
* The NovaSeq X instrument is fully upgradeable to a NovaSeq X Plus instrument. The upgrade is performed by an Illumina Field Service Engineer (FSE) only. Contact your local Sales team for further information.
**Maintenance Notes for the NovaSeq X Instrument:**
* The System Check within the Control Software are programed to test side A only.
* The NovaSeq X instrument comes with 1 wash flow cell and 1 wash cartridge set to allow Side A maintenance washes.
* The Control Software allows the user to open the front doors for Sides A and B for the Air Filter replacement by clicking "Unlock doors" option in the Control Software > Settings.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.
## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://knowledge.illumina.com/instrumentation/general/instrumentation-general-reference_material-list/000009316.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
