Jeebs Posts: 218 Rating: (28)	Hi, As you can see in the picture posted by Tagolover, the first slot is reserved for PowerSupply modules. Both in the main rack and expansion racks. So to answer your question: Slot 1 is reserved for PowerSupply.

So you are free to use any power supply you like. I think the only reason for being able to insert a power supply is for documentation. You can then print out all the components used in the system, including the PS. Regards, Marcjan
