The out of band and inband path goes through this code:
https://github.com/openbmc/phosphor-host-ipmid/blob/master/chassishandler.cpp#L1120

You can follow it to see how the power off occurs. But basically the code uses
phosphor-state-manager interfaces to request the power off which then
runs the appropriate systemd targets.

I think the power button code goes through a similar path of using
phosphor-state-manager systemd targets but is not required for
IPMI interfaces to work.
