Had a M3000 or T4 that arrived dead. A search unearthed
a procedure to reset the service processor to defaults.

Forget the exact runes, but removed the service
processor board, fit a jumper, reinstall, serial
management port terminal at 9600,8,n,1, and there's
a sequence of login, get a preboot prompt, enter
reset all. Preboot menu exits, sp restarts, and
you can login as root, passwd, changeme.
That was years ago, but the solution was on an
Oracle webpage.
