You can perform the ethernet test and see the status whether the hardware port test passed or failed:

it didn't work

I want to use the device in my small network. Is my port disabled because of the version?

Nah it has nothing to do with the version. 

Try re-imaging the appliance: https://support.sophos.com/support/s/article/KB-000036812?language=en_US

You can download the old installers from here: https://download.sophos.com/network/SophosFirewall/installers/index.html

 I installed sw 17.5 version on the device. installation was successful but my lan port disablee :((( I can access the console interface but my port is disabled. 

how do i activate the port

What's the status on the GUI ?

And what is the status of other ports ?

i only access console port. I am giving ip to my lan port number 1. but i can't access the gui interface. 

May be this can help you configure other available ports: https://docs.sophos.com/nsg/sophos-firewall/v17.0.5/PDF/SF%20OS%20Command%20Reference%20Guide.pdf

it didn't work for me

That is all then...

ı need enable lan port 1

ı need enable lan port 1

i finally found it. The device's port order and image order are reversed.
