# Border Gateway FAQs

## What happens to Sensor data if the Border Gateway loses Internet connectivity?

If the Border Gateway loses network connectivity, it queues all the sensor data it receives from Wildfire Sensors and Mesh Gateways. After the network connection has be reestablished, it sends the data to the Silvanet Cloud Platform.

The same process occurs if the Border Gateway is in power saving mode.

## Can I disconnect the solar panel from the Border Gateway?

Dryad does not recommend disconnecting the solar panel from the Border Gateway as this causes the supercapacitors of the Border Gateway to drain. The solar panel also acts as a backup power supply if the PoE is used.

If required, the Solar Panel can be disconnected from the Border Gateway.

## How much time is required for the solar panel to charge the Border Gateway?

The solar panel needs **3 to 4 hour**s to charge the superconductors in the Border Gateway before it comes online.

However, if the PoE is disconnected or if a power failure occurs in the power supply, the solar panel will fully charge the Border Gateway in **1 to 2 days** before it begins operating properly.
