3 To turn off a partition, select [Power Off] for it in the [Power Control] column,
and click the [Apply] button.
The partition is turned off.
Notes: For the reason described below, the operation for shutting down a
C122-E001-10EN
partition must be performed from the OS.
When the [Power Off] operation is selected, and the OS supports ACPI,
the OS can be shut down and the power to a partition can be turned off by
the power-off operation described above. However, if the OS does not
support ACPI, this operation turns the power off without shutting the OS
down.
Even if the OS supports ACPI, power may not be turned off if an
application running under the OS does not support it. This depends on the
OS and application specifications. For details, see the OS and application
manuals.
