3. Loosen the captive screws of the power supply with a Phillips screwdriver until they are completely
disengaged.
4. Grasp the handle of the power supply with one hand and pull it out a little, support the bottom with
the other hand, and pull the power supply slowly along the guide rails out of the slot.
