Power button
The power button switches on or off, the main power to the SAN Volume
Controller 2145-4F2.
To turn on the power, press and release the power button.
To turn off the power, press and release the power button. For a preferred method
of powering off, see the “Powering off a SAN Volume Controller node” topic in the
IBM System Storage SAN Volume Controller: Service Guide.
Note: When the SAN Volume Controller is operational and the power control
button is pressed, the SAN Volume Controller indicates on its front panel
that it is powering off and writes its control data to its internal disk. This
can take up to five minutes. If the power control button is pressed and not
released, an immediate power off is performed without writing the SAN
Volume Controller control data to disk. Service actions are then required to
make the SAN Volume Controller operational again. Therefore, when
powering off, you should not press and hold the power button for more
than two seconds.
