Turning off the compute node

When you turn off the compute node, it is still connected to power through the NeXtScale n1200 Enclosure. The compute node can respond to requests from the IMM2, 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 NeXtScale n1200 Enclosure.

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:

• You can press the power button on the compute node (see Compute node controls, connectors, and LEDs). 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 4 seconds to turn off the compute node.
  Attention: Pressing the power button for 4 seconds forces the operating system to shut down immediately. Data loss is possible.
