Ya know... if you're going to design and manufacture a "modular" power
supply like is in the 11/34A/BA11K, with those nice regulator modules...
wouldn't you think it could be designed so you could pull them out to
replace or add without having to remove the backend of the chassis? That's
just silly.
Perhaps I'm missing it. It appears that you take off the top cover, undo a
holding screw in the back (one per regulator), and undo the connector for
that regulator underneath. But the two screws underneath and inside? Those
don't seem to be removable without taking off the back end of the chassis.
Icky. GrumbleGrumble...
It's not quite as bad... What you do is :
Remove top cover, loosen the top screw holding the PSU ('backend of the
chassis) on each side, and remove the bottmo 2 screws on each side. Then
swing the CPU to the vertical position (That's one reason why the rack
slides have a tilt mechanism) and the PSU will swing away from the
backplane are. Unplug the 8 pin mate-n-lock, remove the 3 screws and
slide the regulator out.
The connecotrs are on the front of the regulators themselves, not the
connectors on the power distrbution PCB.
