# Introduction

This document describes the tools that can be used to configure and debug the ICU Scandinavia AB products based on SBC (Single Board Computer) products working under Linux.

The products are:

* S2GW
* Web Panel
* Relay Box

All these devices can be accessed using SSH protocol. 

A user can obtain terminal access from a PC to device using e.g. [Putty](/tools-for-sbc-products/console-access/putty.md) or [Windows ssh command](/tools-for-sbc-products/console-access/windows-ssh-command.md) which is available in Win10 and Win11.

With a terminal access you can execute Linux commands that will let you check or modify the configuration or debug the operation of a device. The [Midnight Commander](/tools-for-sbc-products/midnight-commander.md) is installed on all the device types to make these tasks easier for persons not acquainted with Linux OS.

To transfer the files between the device and a PC in case of application update or logs download you may use [WinSCP](/tools-for-sbc-products/file-transfer/winscp.md) or [Windows scp command](/tools-for-sbc-products/file-transfer/windows-scp-command.md) which is available in Win10 and Win11.

The PC used for the tasks is running under Windows OS. Alternatively Linux machine may be used, where the similar tools are also available but the details will be different.
