MOTM

I have several of these.  As Larry said you can mount the assembled MOTM 
power supply to the front or to back of the case.  If you choose the 
front, it is of course the easiest option, but you lose 3U of module 
space <shudders>.  If you choose the back, you probably want to mount it 
on the opposite end from the opening made for this purpose in the 
cabinet.  I did it this way initially.

A drawback to this approach is that with the power supply protruding its 
4-inch height, you can mount only shallow modules in front of it.  I 
later came up with the following alternative.

I unmounted both the supply and the power distribution board from the 
MOTM panel.  The power supply is rotated so that it is parallel to the 
long dimension of the cabinet now and mounted to the wood so that its 
smallest dimension, about 2.5 inches, takes up space behind the panel 
and you can mount deeper modules in front of it.   I used an angle 
bracket on the end where the hole isn't easy to reach because of the 
transformer.  The AC wiring is not changed.  The power distribution 
board is mounted near the back of the cabinet more toward the center.  
You can upgrade to a MOTM-960 or 990 distribution board.  I used some 
16-gauge wire to connect up the 960 to the supply.  I will take some 
photos of this.  I'm about to do a bit of rewiring to upgrade a cabinet 
to the HBB15-1.5-A Power One unit.  A MOTM-900 might provide sufficient 
power for the 26U cabinet, if all MOTM.   But I cramed as many 
submodules behind each panel as I could, and I have some non-MOTM 
modules that consume more power than the MOTM average.  So my power 
requirements are a bit more.

By the way, I very highly recommend Larry Hendry's mounting rails and 
Synthesis Technology logo end piece for this cabinet.  I got pretty good 
at doing it by the time the fourth cabinet was done!  It is really not 
difficult.  I am always rearranging modules as I add more cabinets, and 
the rails make it a snap.
