I never made a diagram. All I did was solder down a terminal block to each end of a piece of prototype board. I connected the power lines using some small inductors I had and bypassed power to ground using (I think) 0.01 caps.
I mounted the Cisco power supply block to the inside of the case using hot glue. As I remember the Cisco PS needs to have one line grounded to make it turn on. I figured that out when I got zero volts on the cable. On Sat, Aug 25, 2012 at 3:41 PM, Edgardo Molina <[email protected]> wrote: > Dear Chris, > > Good afternoon.
