  It's a multi-step process, and every system is different. It's not just a matter of flip the switch and wait for it to come up. If you're looking at something really primitive, you might even literally have to toggle in a boot loader program. These 2 Youtube videos show how to initialize an S/390. The top comment on the second video is really good, too. https://www.youtube.com/watch?v=ytMgyrZm87A https://www.youtube.com/watch?v=ytMgyrZm87A https://www.youtube.com/watch?v=qrKbh5HwF3Q https://www.youtube.com/watch?v=qrKbh5HwF3Q
