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.
The operating systems requires an orderly shutdown before you turn off the file
module. If you have a problem powering off the system, refer to Administering >
Turning on and turning off the system > Turning off the system, located in the
Storwize V7000 Unified Information Center (http://publib.boulder.ibm.com/
infocenter/storwize/unified_ic/index.jsp).
CAUTION:
The power-control button on the device does not turn off the electrical current
supplied to the device. The device might also have more than one connection to
dc power. To remove all electrical current from the device, ensure that all
connections to dc power are disconnected at the dc power input terminals.
(C031)
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, refer to
Administering > Turning on and turning off the system > Turning off the system,
located in the Storwize V7000 Unified Information Center (http://
publib.boulder.ibm.com/infocenter/storwize/unified_ic/index.jsp).
The Type will change from Unknown to NAS after initial setup of the file modules
is complete.
