On the right vertical post of the rack you mount two hinges. Each hinge has
a pin that simply goes through a hole of the vertical post, and one screw.
Yep, I got the installation instructions in the manual, which are
wonderfully detailed WRT rackmounting. You may not have noticed this
though.... If you are mounting the 6125 anywhere except the very top of the
rack - no problem. However, if you are mounting it right at the very top you
will want to know something that the manual isn't clear on. Those pins you
mention above - they look like they are threaded and you just screw them
into the hinge from the top. But if you look very closely, you'll see that
the pins can be screwed into the hinges *from the bottom* until they stick
out of the top the right way. You won't get it mounted in the very top of a
rack unless you do it that way (depending on your rack of course).

As far as I know, there is one pin header on the horizontal circuit board
for connection to the controller and one cable on the vertical board that
goes to the PSU. The other side of the PSU (rear in the rack) has the mains
power cable (cannot be detached).
Yep, they are different then. The desktop power supply itself is identical
but the metalwork is not. In addition, the power cord is removable on the
desktop version. I will have to make "non-standard adjustments" for that :|

It is heavy, I estimate between 40 and 50 kilo. Not good for your back, but
when you're on your own (unloading the van) ...
Tell me about it. After I mounted the 6125 I noticed the blue cover door
wouldn't open all the way due to clearance on the left front of the rack.
Further scrutiny revealed that $previous_owner mounted the two front
vertical rails with a slant. The front vertical rails are flush with the
front of the rack at the bottom, but at the top they are back about 1/2
inch. So today I am unracking everything in the rack, adjusting the two
front vertical rails, and then re-racking everything. What a major pain. My
fault though - I should have noticed this before I got all the way to the
top in putting stuff in the rack.
