Word of warning
We strongly advise against setting a static/fixed IP address for a Chromebox. We manage the Chromeboxes remotely via the Chrome Management. When the network infrastructure is changed the access to box will be lost permanently. The preferred solution is to reserve static/fixed address for the box on the DHCP server.
If you want to set a static/fixed IP address for the box anyway, we won't be able to reliably provide remote service.
1. Stop the kiosk mode of the Chromebox
