Remotely accessible management processors absolutely rock.  I'd hate
to do without one on a machine that was not easily physically
accessible.

Demonstration (on an hp4640):

% telnet iceberg-mp                                /d0/iso/hp/firmware
Trying 192.168.1.10...

Execution of this command irrecoverably halts all system processing and
I/O activity and restarts the computer system.

Type Y to confirm your intention to restart the system: (Y/[N]) n
n                                                                
   -> SPU hardware has not been reset.
