It's possible. One thing at a time though, I'll try the 170 first.

Yeah, thats how most of the POWER3/POWER4 series service processors work.  You
can power them up, but not down.  You can get back to the service processor by
issuing a powerdown from the OS via rtas.  (Basically, a 270/170 never fully
powers off, its allways watching the serial port for someone to hit enter and
bring up the menu)

Yeah, I meant 150 vs B50 and 170 vs 270.
