Initiating a delayed power off
You can use the power button on the control panel to initiate the delayed power off (DPO) feature.
Attention: Using the power button
on the control panel to power off the system might cause unpredictable
results in the data files, and the next IPL will take longer to complete.
Some servers do not respond to the power-off sequence unless the system is in manual operating mode. If necessary, set the system operating mode to manual mode.
To initiate a DPO, do the following steps:
- Press and hold the power button on the control panel for four seconds. After one second, a countdown time is displayed. The default countdown time is four seconds.
- Continue to press and hold the power button until the countdown time reaches zero, and then release the power button. The DPO is initiated.
To cancel the DPO before it starts, release the power button
before the countdown reaches zero. If the power button is depressed
for less than one second, no countdown time is displayed, and the
power-off function is not initiated.
