As the ME3600x is designed to run with two PSU and will not even start
when only one PSU is present, I do not think it's good design to
simply drop the entities.

Ironically, the 6500 which has a distinct fan tray and thus may run
with one PSU only is designed that way...

For some reason, I woke up at 0700 sharp (on the weekend, yay) so I
played with that for a few more few hours and... sadly no.


Thanks,
