# Power Supply Options

You can power the **Aranet Gateway Pro** in two ways: **USB-C** or **PoE**.

#### USB-C power (5 V DC)

Use a USB-C power adapter that provides **5 V DC** and **at least 1 A**.

The power adapter is **not included** in the original package. This helps reduce electronic waste. You can use any compatible adapter, or buy one separately.

#### Power over Ethernet (PoE, 802.3af)

The Gateway Pro can be powered through the **Ethernet (RJ45)** port.

You can supply PoE from:

* a PoE-enabled Ethernet switch (**802.3af**), or
* an **active PoE injector** (for example, **TDAPOE03**), or
* the **Aranet PoE adapter** (**TDAPOE04**).

{% hint style="warning" %}
If you use **third-party PoE** equipment, make sure it’s compatible with the Gateway Pro and its power requirements.
{% endhint %}

#### Power off

To power off the Gateway Pro, disconnect its power source:

* unplug the **USB-C** cable, or
* unplug the **Ethernet** cable (if using PoE).

The device shuts down safely after power is removed.

## 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://help.aranet.com/gateway/gateway-pro/firmware-and-hardware/specifications/power-supply-options.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.
