Setting Up Home Network Scanning - Mac & PC

I'm trying to setup my Workcenter 4150 to my home network and I'm not quite sure how to do this. 

I can't seem to load the Webservices by typing in the IP but it won't load so it seems I can't setup my network scanning...which is the main reason. 

Is there a simple step by step procedure I can follow to do this from plugging in the Ethernet Card to getting the network scanning running?
