shutdown the IOP, after issuing the shutdown command, issue a
Windows NT Shutdown without Restart then power off the system
when prompted.

This command allows for an Operating System restart that may be
necessary when changing the configuration for Windows NT or

a shortcut to restarting the OS without completely shutting down the
servers or the HPAA system.
