To turn on the power, press and release the power button. You must have a pointed device, such as a pen, to press the button.
To turn off the power, press and release the power button. For more information about how to turn off the IBM Spectrum Virtualize node, see MAP 5350: Powering off a IBM Spectrum Virtualize node.
Attention: When the node is operational and
you press and immediately release the power button, the IBM Spectrum Virtualize writes
its control data to its internal disk and then turns off. This
can take up to five minutes. If you press the power button but do
not release it, the node turns off immediately without the IBM Spectrum Virtualize control
data being written to disk. Service actions are then required to make
the IBM Spectrum Virtualize operational
again. Therefore, during a power-off operation, do not press and hold
the power button for more than two seconds.
Note: The 2145 UPS-1U does
not turn off when the IBM Spectrum Virtualize is
shut down from the power button.
