# Powering
Once you have unboxed the camera and all other components, power on and initialize the camera (it is recommended to do this prior to on-site installation).
* Option 1 – PoE Switch (48V and 0.52A); (can both power and access the system)
* Option 2 – DC power supply (12V and 2.0A); (can power the system, but requires an ethernet cable to access and communicate). Note: An ethernet cable must also be connected if using the DC power supply, to configure the camera.

## 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://docs.rekor.ai/edge-pro/connecting/powering.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.
