Turning the MAX5 on and off
Because the MAX5 expansion module is controlled by the server, turning on the
MAX5 refers to connecting the MAX5 power cord to the power source and pressing
the power-control button on the host server that is connected to the MAX5
expansion module and is configured to identify the expansion module. Normally, the
operating system on the server starts, and the server issues a power-on request to
the MAX5. The IBM MAX5 for System x (MAX5) memory expansion module is
turned off only if the connected server issues a power-off request and you
disconnect the MAX5 power cord from the power source. You cannot turn off the
MAX5 expansion module manually.
Statement 5:
CAUTION:
The power control button on the device and the power switch on the power
supply do 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.
You can disconnect the MAX5 expansion module power cords from the power
source to shut off all power immediately without damaging the MAX5, but it might
cause an unrecoverable error and loss of data on the connected server.
