# Starting and Stopping the Platform Operating System

User Access: Administrators, Managers.

SM Console Usage:

Follow these steps to start or stop the platform operating system:

1. Click Management Platform Operations from the menu bar.
2. Select an option.

   Option | Description
   --- | ---
   Power On / Restart | The Power On/Restart operation starts the platform operating system.
   | The Boot into BIOS Setup option stops the boot process allowing you to modify the BIOS settings from the platform console. Once you have selected this option to boot to BIOS setup, you must then access the BIOS configuration screen to change BIOS settings. To do so remotely, you can log in via an SSH client or from the SM Console by choosing Troubleshooting>SP SSH Console. You can then execute the platform console command.
   | The Forced Restart option bypasses the operating system shutdown stage during a system restart and may cause a loss of data.
   Shutdown / Power Off | The Shutdown/Power Off operation shuts down the platform operating system and powers off the machine.
   | The Forced Power Off option bypasses the operating system shutdown stage and may cause a loss of data. The Forced Power Off option is useful when you need to force a shutdown.

3. Click the button.
4. Click the OK button on the confirmation prompt.
   The operation performs on the server. The help text displays any processing and results messages.
   The current state is reflected in the System Status button, allowing you to monitor the progression of these operations.

SM Command Usage:

You can also use the platform subcommands to perform these functions at the command line.

Notes

- If the power is currently off, the Shutdown/Power Off operation simply returns a message stating that it could not be executed due to the current state.
- Refer to troubleshooting information for help with operating system problems.
