Turning The Max5 On And Off - IBM System x3690 X5 Installation And User Manual

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.
