Infrastructure Software

Ok so im 20 years old and i have never used linux, solaris or unix in a profesional way. Im working with some relatives this summer and a couple of days ago we got a call from a customer asking if we could help with the installation of some Sun servers, i dont know how but everyone pointed at me(i program a lot(php, java, ajax, jsp, you know) and config a lot of computers here at the office). So now i have this:

-1 Netra
-4 Sunfire Servers
-2 3Teras HD

All that in a rack, with no user interface.

So i talked to the guys in charge and they told me the netra should install the sunfires and admin them on the fly in a 3 layer confirgutation. Right will this is the first time i touch a rack like this(i have used hp and dell servers running on DotNOT). So i tried to conect to the netra and bang first problem, i didnt know the ip of it to telnet so i called the owner of the rack and they got the netra to sun and they format it, and lended us a workstation to intall the sunfires...

So what i need to do:

-Connect the workstation
-Somehow telnet the sunfires so they get installed
-Somehow connect to the netra and config it to admin the sunfires

Im not asking you guys to do my job, but i have been all over the sun site and google looking for manuals to real, tutorials to chug down and reference's to have around, and ive got no materials on how to get started, so any tip, idea, reference will help me a lot!
