The following procedure describes how to stop a system that is not managed by a Hardware
Management Console (HMC).
1. Log in to the system as a user with the authority to run the shutdown or pwrdwnsys (Power Down
System) command.
2. At the command line, enter one of the following commands:
v If your system is running the AIX
®
operating system, type shutdown.
v If your system is running the Linux operating system, type shutdown -h now.
v If your system is running the IBM i operating system, type pwrdwnsys. If your system is
partitioned, use the pwrdwnsys command to power down each of the secondary partitions. Then,
use the pwrdwnsys command to power down the primary partition.
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.
3. Set the power switches of any devices connected to the system to off.
4. 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.
