Turning Off The Compute Node - IBM Flex System x440 Compute Node Installation And Service Manual

v You can turn on the computer node through the Wake on LAN feature. The
computer node must be connected to power (the power LED is flashing slowly)
and must be communicating with the Chassis Management Module. The
operating system must support the Wake on LAN feature, and the Wake on
LAN feature must be enabled through the Chassis Management Module
interface.

Turning off the compute node

Use this information for details about turning off the compute node.
About this task
When you turn off the compute node, it is still connected to power through the
IBM Flex System chassis. 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 IBM 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
shutdown process (if this feature is supported by the operating system). See
your operating-system documentation for more information.
v You can press the power button on the compute node (see "Compute node
controls, connectors, and LEDs" on page 10). This starts an orderly shutdown of
the operating system, if this feature is supported by the operating system.
v 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.
v You can turn off the compute node through the CMM power command, the
CMM web interface, or IBM Flex System Manager management software (if
installed).

– From the CMM web interface, select Compute Nodes from the Chassis
Management menu. For more information, see the "IBM Flex System Chassis
Management Module: User's Guide" at http://publib.boulder.ibm.com/
