File module power features:
When the file module is connected to a power source but is not turned on, the
operating system does not run, and all core logic except for the integrated
management module is shut down. However, the file module can respond to
requests from the integrated management module, such as a remote request to turn
on the file module. The power-on LED flashes to indicate that the file module is
connected to power but is not turned on. The power on LED is found in the front
of the file module.
Powering on the file module
Approximately 3 minutes after the file module is connected to power, the
power-control button becomes active. Also, one or more fans might start running
to provide cooling while the file module is connected to power. You can turn on
the file module and start the operating system by pressing and releasing the power
on button. The power on button is located at the front of the file module.
Turning off the file module
When you turn off the file module and leave it connected to power, the file
module can respond to requests from the integrated management module. For
example, it can respond to a remote request to turn on the file module. While the
file module remains connected to power, one or more fans might continue to run.
To remove all power from the file module, you must disconnect it from the power
source.
Important: To view the error LEDs on the system board, leave the file module
connected to a power source.
Some operating systems require an orderly shutdown before you turn off the file
module. See your operating-system documentation for information about shutting
down the operating system.
CAUTION:
The power on button on the device does not turn off the electrical current supplied
to the device. The device also might have more than one power cord. To remove
all electrical current from the device, ensure that all power cords are disconnected
from the power source.
Press and release the power on button to start an orderly shutdown of the
operating system and turn off the file module, if your operating system supports
this feature
Attention: If you have a problem powering off the system, see the Storwize
V7000 Unified Problem Determination Guide documentation CD for more information
about light path issues.
