I do believe the tick indicates that the shub has booted up correctly, locked onto the downstream channels and established its connection. Can you connect to the shub and read the logs and see what is going on with everything else? Assuming you are using the shub in router mode you want to go to
http://192.168.0.1 and click on router status in the top right and look at the info in each of the tabs. I was going to post some screen shots put photoshop is playing up for some reason.
