Shut down the system by any means you can. Once it is at standby the service processor menus are available over the built in (not PCI adapter) serial ports.
If you don't have authority as a non root user to issue a shutdown you will need to push the power button.
I'd be suprised if the other platforms you mention would allow a halt of the system from a login prompt or a normal user login.
If they did there would be systems going down all over the place!
