# Powering ON the Camera - Self-Check

The A6K-Lite camera will power on automatically when the entire system (NavBox) is connected to a power supply (make sure the LiDAR/Camera cable is connected between NavBox and camera). 

At boot-up, the camera will perform a **self-check** to guarantee proper functionality.

During the self-check, the Status LED of the camera will be constant RED and the camera will trigger a total of 2 times (the Activity LED will signal a trigger event by flashing RED). 

After a successful self-check, the Status LED will turn to constant GREEN. Otherwise, if the self-check failed, the Status LED will start flashing RED. If this happens, the camera will not be operational. Please refer to section [Troubleshooting](/hardware-and-interfaces/camera/a6k-lite-camera/troubleshooting.md) of this manual.

Once the Status LED is GREEN, the camera is ready for operation and can be used via Spatial Explorer.<br>

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.phoenixlidar.com/hardware-and-interfaces/camera/a6k-lite-camera/powering-on-the-camera.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
