Need Sharp AR-168D ip address

[despierto]

I inherited an old sharp AR-168D MFP in our lab, and I need to set it up for network printing. Unfortunately I can't seem to find any information in the manuals as to tell how the IP address is configured.

They all say "Go to a browser and type in the IP Address..." Great. What IS the IP address? Where do I find it?

We have the AR-NB2N network add-on, if that helps anyone.

Thanks in advance!
