The power button turns 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 MAP 5350: Powering off a SAN Volume Controller node.
Note: When the SAN Volume Controller is
operational and you press and immediately release the power button,
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 you
press the power button but do not release it, an immediate power off
occurs 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.
Attention: The SAN
Volume Controller 2145-4F2 node
is the only SAN Volume Controller model
that is supported by the 2145 UPS.
If a SAN
Volume Controller 2145-4F2 is
turned off for more than five minutes and it is the only SAN
Volume Controller 2145-4F2 that
is connected to a 2145 UPS,
the 2145 UPS also
turns off. To turn on the SAN
Volume Controller 2145-4F2,
you must first turn on the 2145 UPS to
which it is connected.
Note: The 2145 UPS-1U does
not turn off when the SAN Volume Controller node
is shut down from the power button.
