Turning off the compute node
When you turn off the compute node, it is still connected to power through the IBM Flex System
Enterprise Chassis. The compute node can respond to requests from the service processor, 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 Enterprise Chassis.
Before you begin
Shut down the operating system before you turn off the compute node. See the operating-system
documentation for information about shutting down the operating system.
About this task
To turn off the compute node, use one of the following methods:
Procedure
v
Turn off the compute node by pressing the power-control button for at least 5 seconds.
Note:
The power-control LED can remain on solidly for up to 1 minute after you push the
power-control button. After you turn off the compute node, wait until the power-control LED is
flashing slowly before you press the power-control button to turn on the compute node again.
If the operating system stops functioning, press and hold the power-control button for more than 5
seconds to force the compute node to turn off.
v
Use the management module to turn off the compute node.
The power-control LED can remain on solidly for up to 1 minute after you initiate the power-off
process. After you turn off the compute node, wait until the power-control LED is flashing slowly
before you initiate the power-on process from the Chassis Management Module (CMM) to turn on the
compute node again.
Use the management-module Web interface to configure the management module to turn off the
compute node if the system is not operating correctly.
