Fixed IP address, Turn off DHCP server

Hallo,
I have similar question as in topic [Client DHCP ne se connecte pas au Serveur]
Skycontroller wants to be DHCP server after connection via ethernet cable.
Is it possible to configure computer between Samsung Galaxy tablet and ethernet port on the Skycontroller?
I need to turn off DHCP server and I would like to assign fixed IP address from our subnetwork.
Is possible to configure computer inside Skycontroller via SSH?
Thanks
Jindrich
