According to the manual the server is capable of using DHCP, but can also be 
configured with a static IP address. Of course I cannot be sure how it is 
configured at the moment.
There is a reset button on the unit, but that only resets the password. At 
least that's what the manual say. (I have tried it...)

I have tried the default address, but got no reply from the unit. 
I made a little script utilizing nmap to scan all the addresses between 
192.168.0.0 and 192.168.255.255. (one network at a time of course). 
Unfortunately I still got no reply.

As I'm not very good at making scripts yet, I had to look through all the 
generated log files to check whether an address was found or not. Took a bit 
of time. ;-)  
Seriously, I don't know enough about Linux and the command line tools to make 
any advanced scripts yet. That'll probably come along the way.
