Yellow Machine connectivity

Hi,
New to this forum. I didn't know where to post this question because there is no particular place for this but since it is a peripheral to the computer, I thought I would post it over here.
I have a Yellow machine Server P400T at the office and decided to use it. I don't have any documentation or any kind of CD. I want to know how to physically connect to the PC? I have connected the network cable from my PC to one of the 8 LAN ports on the yellow machine. Then turned the PC on, let it get into windows and the turned the yellow machine ON. Then in the explorer window, typed in the address : 172.16.1.255 but gives me the error, "Internet Explorer Cannot Display The Webpage".
My network settings is set to automatically get the IP address. What else do I need to do? What am I doing wrong? Do I need the installation CD?
Please help.
Thanks in Advance.
