  • Power down the unit you are replacing the power module(s) in and unplug the power.
  • Open the back of your unit with a Philips screwdriver.

  • Locate the failed module, and loosen the screw on the right side with a slotted (flathead) screwdriver.

  • Once loosened, pinch the pin to the right of the screw, and pull the module out using the grab handle on the left side.

  • Insert the new module (make sure it clicks into place) and tighten the screw.

  • You can now safely power back on your unit.
