Disconnect power cords to completely remove power.
Caution -
Equipment damage. Do not disconnect power cords when system is in full
power mode.

When the server is in standby power mode, the service processor is
powered on but the host is powered off.

If the server is completely powered off, plug in the power cords to apply
standby power.

to remove host power.
You can power the host off gracefully, or immediately.
