• 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).
