The power button turns main power on or off for the SAN Volume Controller.
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 SAN Volume Controller node,
see MAP 5350: Powering off a SAN Volume Controller node.
Attention: When the node is operational and you press and immediately
release the power button, the SAN Volume Controller indicates
on its front panel that it is turning off and writes its control data
to its internal disk. 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 SAN Volume Controller control
data being written to disk. Service actions are then required to make
the SAN Volume Controller 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 SAN Volume Controller is
shut down from the power button.
