Setup and Test

Place one PSU in the shelf . Switch the Rack ON by placing one breaker on. The two
breakers duplicate power to each shelf and the shelves will still function if one power supply
fails though the LED indicators on the power supplies will not be on. The PSU should show a
green LED and one supply fail LED. Switch on the second breaker and the Red LED should
extinguish.
Switch off and place the second PSU in the shelf and repeat the process described in the
paragraph above.

Place a SC Card into the shelf to provide a load. Switch both breakers on and measure and
record the DC voltage at the o/p of each PSU.
