The secret trick is, after you go to the Downloads and Software and find the software (OnCommand System Manager, etc), and click the View & Download button, you have to scroll all the way to the bottom of the page, and they cleverly hide it as a link labeled "CONTINUE". Very unintuitive. They're more concerned that you read every letter on the page, than they are that you get what you came for. ... in my opinion.
But WAIT, there's MORE... Then you have to accept the EULA page, and at the bottom of that, it says something like "To download System Manager software, click the System Manager Installation File (approximately 44 MB)."
