## Power Off the Server (SP Command)

You can use the SP to perform a graceful shutdown of the server. This type of shutdown ensures that all of your data is saved and that the server is ready for restart.

Note - You can also use the Power button on the front of the server to initiate a graceful server shutdown. (See Power Off the Server (Power Button - Graceful).) This button is recessed to prevent accidental server power off.

Note - For additional information about powering off the server, refer to the SPARC T4 Series Servers Administration Guide.

1. Log in as superuser or equivalent.

   Depending on the type of problem, you might want to view server status or log files. You also might want to run diagnostics before you shut down the server.

2. Notify affected users that the server will be shut down.

   Refer to the Oracle Solaris system administration documentation for additional information.

3. Save any open files and quit all running programs.

   Refer to your application documentation for specific information for these processes.

4. Shut down all logical domains.

   Refer to the Oracle Solaris system administration documentation for additional information.

5. Shut down the Oracle Solaris OS.

   Refer to the Oracle Solaris system administration documentation for additional information.

6. Switch from the system console to the `->` prompt by typing the `#.` (Hash Period) key sequence.
7. At the `->` prompt, type the `stop /SYS` command.
8. Unplug all power cords from the server.

   | Caution - Because 3.3v standby power is always present in the server, you must unplug the power cords before accessing any cold-serviceable components.
