Installing Nerve

Requirements for installing Nerve on the device:

In addition, a workstation is required to prepare the bootable USB drive. Connect the monitor and the keyboard to the KBox A-250.

Before beginning with the installation, make sure that the device will boot from the USB drive. Press Del when the device is booting to enter BIOS and change the boot device settings.

On Windows

1. Download the Nerve_Blue_USB-installer_2.3.1_for_kontron-kbox-a-250.img.tar.gz from the Nerve Software Center to a workstation.
2. Extract the Nerve_Blue_USB-installer_2.3.1_for_kontron-kbox-a-250.img.tar.gz file to retrieve the Nerve_Blue_USB-installer_2.3.1_for_kontron-kbox-a-250.img file. Depending on the program used, the file might need to be extracted more than once.
3. Transfer the extracted Nerve_Blue_USB-installer_2.3.1_for_kontron-kbox-a-250.img file to the USB drive using Rufus.
4. Plug the USB drive into a USB port of the Nerve Device.
5. Make sure that the device will boot from the USB drive and power on the device.

The setup will start automatically and take a few minutes to complete. Select OK when the installation is complete and remove the USB drive. The device will reboot and reach a log in screen, asking for host access log in credentials. Make sure that the device will boot from the hard disk before rebooting the device.

On Linux

1. Download the Nerve_Blue_USB-installer_2.3.1_for_kontron-kbox-a-250.img.tar.gz file from the Nerve Software Center.

2. Enter the following commands to extract the Nerve_Blue_USB-installer_2.3.1_for_kontron-kbox-a-250.img.tar.gz file and transfer the extracted file to the USB drive:

   tar xf Nerve_Blue_USB-installer_2.3.1_for_kontron-kbox-a-250.img.tar.gz
   sudo dd if=Nerve_Blue_USB-installer_2.3.1_for_kontron-kbox-a-250.img bs=4M of=/dev/sd<drivename> status=progress
   sync
   

   Note

   Make sure to replace <drivename> with the system name of the USB drive.

3. Plug the USB drive into a USB port of the Nerve Device.

4. Make sure that the device will boot from the USB drive and power on the device.

The setup will start automatically and take a few minutes to complete. Select OK when the installation is complete and remove the USB drive. The device will reboot and reach a log in screen, asking for host access log in credentials. Make sure that the device will boot from the hard disk before rebooting the device.

Finding out the IP address of the device

Due to the limited availability of ethernet ports, Nerve does not offer a designated port and interface for host access and management purposes on the Kontron KBox A-250. The IP address of the wan interface that is mapped to physical port ETH 2 is required to start using Nerve. Depending on the network access the node has, this needs to be done differently.

The node has network access

If the node has network access, an IP address will be assigned to the wan interface by a DHCP server. Follow the instructions below to find out the IP address of the wan interface.

1. Connect a keyboard and a monitor to the device.
2. Power up the device once Nerve is installed.
3. Enter the login credentials for host access once the system asks for host login. The login credentials can be found in the customer profile.

4. Enter the following command to display the IP address of the wan interface:

   ip a s wan
   

The IP address is displayed next to inet in the output the system gives. This IP address is required to access the Local UI in the instructions below.

The node does not have network access

In case of the node not having network access, the IP address of the wan interface has to be set manually. For simplicity, the IP address of the wan interface will be set to 172.20.2.1 — the IP address of the host.

1. Connect a keyboard and a monitor to the device.
2. Power up the device once Nerve is installed.
3. Enter the login credentials for host access once the system asks for host login. The login credentials can be found in the customer profile.

4. Enter the following commands to open the wan interface configuration:

   cd /etc/network/interfaces.d
   sudo nano wan
   

5. Enter the host access password if prompted.

6. Edit the configuration the following way:

   auto wan
   iface wan inet static
     bridge_ports eth0
     address 172.20.2.1
     netmask 255.255.255.0
   

7. Enter Ctrl+S to save the configuration.

8. Enter Ctrl+X to exit the Nano editor.

9. Enter the following command to apply the changes to the wan interface by restarting the networking services:

   /etc/init.d/networking restart
   

10. Enter the host access password if prompted.

With the wan interface IP address set to 172.20.2.1 the Local UI can be reached at http://172.20.2.1:3333/.

Activating the Nerve license

After the installation, the product license needs to be activated so that Nerve can be used on the device. Connect a workstation to port ETH 2 and configure the network adapter of the workstation. The IP address has to be in the same range as the IP address of the wan interface with a 255.255.255.0 subnet mask. Refer to the chapter above on how to find out this IP address.

Access the Local UI at <wanip>:3333 in a web browser and refer to License activation in the user guide for more information.

Accessing the Local UI and registering the device

With the license activated, the node needs to be registered for use in the Management System through the Local UI. To access the Local UI, first connect a workstation to port ETH 2 and configure the network adapter of the workstation. The IP address has to be in the same range as the IP address of the wan interface with a 255.255.255.0 subnet mask. Refer to the chapter above on how to find out this IP address. The credentials for the Local UI found in the customer profile are also required.

1. Access the Local UI at <wanip>:3333 in a web browser.

2. Log in with the credentials from the customer profile.

   

Continue with Node configuration for information on how to start registering the device in the Management System.

Physical ports and network interfaces

Below is a depiction of the node internal networking adapted to the KBox A-250 hardware. Refer to Node internal networking for more information. The table offers a quick overview of the network interfaces that can be reached through the physical ports of the KBox A-250.
