Where to Go From Here
Regardless of why you shut down a system, you'll probably want to return
to run level 3 where all file resources are available and users can log in.
For instructions on bringing a system back to a multiuser level, see Chapter 13, SPARC: Booting a System (Tasks) or Chapter 14, x86: Booting a System (Tasks).
 How to Shut Down a Standalone System
Use this procedure when you need to shut down a standalone system.
Become superuser. Shut down the system.
run-level identifies the new run level.
For more information, see init(1M).
Use the following table to verify that the system is at the run level
that you specified in the init command.

2 (multiuser level) | # | # |
0 (power-down level) | ok or > | type any key to continue |
