Power off the compute node
Use this information for details about turning off the compute node.
When you power off the compute node, it is still connected to power through the Flex System chassis. The
compute node can respond to requests from the XClarity Controller, such as a remote request to turn on the
compute node. To remove all power from the compute node, you must remove it from the Flex System
chassis.
Before you power off the compute node, shut down the operating system. See the operating-system
documentation for information about shutting down the operating system.
The compute node can be powered off in any of the following ways:
• You can press the power button on the compute node. This starts an orderly shutdown of the operating
system, if this feature is supported by the operating system.
• If the operating system stops functioning, you can press and hold the power button for more than four
seconds to power off the compute node.
Attention: Pressing the power button for 4 seconds forces the operating system to shut down
immediately. Data loss is possible.
• You can power off the compute node through the CMM power command, the CMM web interface and
the Lenovo XClarity Administrator application (if installed).
– For more information about the CMM power command, see the Flex System Chassis Management
