The following procedure describes how to stop a system that is not managed by a Hardware Management Console (HMC).

After you stop the operating system, or if you need to use the control panel power button to power off the system see, Using the control panel power button to power off.

Prepare to stop the system

Before you stop the system, do the following:

If an Integrated xSeries® Adapter (IXA) is present on the system, shut it down using i5/OS® options.
Ensure that all jobs are completed and end all applications.
Ensure that the operating system is stopped. Failure to do so can result in the loss of data.
Record the IPL type and IPL mode from the control panel display to help you return the system to this state when the installation or replacement procedure is completed.
Write down the information displayed on the control panel if you are stopping your system due to an error or to make a repair. For more information, see Collecting reference codes and system information.

Stop the system

To stop a system, follow these steps:

Log in to the system as a user with the authority to run the shutdown or pwrdwnsys (Power Down System) command.
At the command line, enter one of the following commands:
- If your system is running AIX®, type shutdown.
- If your system is running i5/OS, type pwrdwnsys *immed.
- If your system is running Linux®, type shutdown -h now.
The command stops the operating system. The system power turns off, the power-on light begins to slowly blink, and the system goes into a standby state.
Set the power switches of any devices connected to the system to off.
Unplug any power cables that are attached to the unit from electrical outlets. Ensure that you unplug power cables from peripheral devices, such as printers and expansion units.
Important: The system might be equipped with a second power supply. Before continuing with this procedure, ensure that all power sources to the system have been completely disconnected.
