Re-install Sunblade 2000 with new solaris OS release

Hi all,
I am a newbie with sunblade 2000 hardware.
I need to format the server and re-install a new solaris release, and I don't know how to do... If I try to boot on a CD, it didn't boot, Is it normal ?
Do I need to go to a bios ? what is the key sequence ? to plug a console ? on which port ? with which device ?
Can you please help me ?
Thank you in advance
Regards
Richard
