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 turn 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 turned off in any of the following ways:
v The compute node can turn off automatically as part of the operating system
v You can press the power button on the compute node (see "Compute node
v If the operating system stops functioning, you can press and hold the power
v When you press the power-control button on any compute node in a single
v You can turn off the compute node through the CMM power command, the

Attention: Pressing the power button for 4 seconds forces the operating system
to shut down immediately. Data loss is possible.
