Jochen,

>>- one H785 battery backup regulator module
>>- one H745 -15 PSU module
>>- two H7441 +5V PSU modules

the latter are 32A regulators, right? - If so, and particularly if part
of the box is from a different source, you may want to make sure you
have the later revision of the power distribution gear.

The older version might let out some magic smoke: it was designed for
the (IIRC) H744 brick (25A max.). When the old distribution is used with
the later, stronger H7441, and with a stuffed backplane, it can get
overloaded. I may be able to look up the critical part numbers if you
cannot find them elsewhere.
