You can use the power button on the control panel to initiate
the fast power off (FPO) 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 to manual operating mode. See Putting the physical
control panel in manual operating mode.
To initiate a fast power off (FPO), do the following:
- 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 until after the delayed power off (DPO) is initiated. A new DPO-FPO separation count of 10 seconds is started.
The separation count is used to distinguish a DPO from an FPO. During this interval, DPO progress system reference
codes are displayed, followed by the countdown time.
- Continue to press and hold the power button for 10 seconds
until the DPO-FPO separation count reaches zero, and then release
the power button. When the
FPO count expires, A100800A is displayed and the FPO
is initiated. This action is equivalent to entering a function 08.
If you release the power button during the DPO-FPO separation
count, the FPO is canceled, and the DPO continues.
If you continue to press the power button after
the DPO-FPO separation interval has expired, or if you press and hold
the power button while a DPO is in progress, the FPO countdown begins
again and A1008009 is displayed.
