1. First you must write the image to your microSD card that is in your Ethernet adapter. To do this, remove the microSD card from 8Eth1 adapter and using the card reader connect it to the PC. Using the program "win32diskimager" (for Windows) or "dd" (for Linux), open the image in the program. The image must be unpacked on microSD.
2. Then you need to remove the microSD card from the card reader and insert it back into 8Eth1 adapter. When you start the Ethernet adapter will receive an address via DHCP.
3. Next, you need to connect via SSH on port 36000 (not 22!). For example: ssh cubie@172.16.1.101 -p 36000
Use login - cubie. The password is printed on a label attached to the device. If it is missing, please contact support.
4. Finally, setting a static address. Enter the following at the command prompt:

sudo mount -o remount,rw /
sudo nano /etc/network/interfaces

5. Сhange static to dynamic, address, netmask, gateway and dns-nameservers. Below is an example. After all the above steps, you need to restart the adapter.

auto eth0
iface eth0 inet static
        address 172.16.1.101
        netmask 255.255.255.0
        gateway 172.16.1.1
        dns-nameservers 172.16.1.1
		
sudo reboot
