2. Disconnect the power cord.
3. Loosen the captive screws of the power module with a Phillips screwdriver until they are completely
disengaged.
4. Grasp the handle of the power module with one hand and pull it out a little, support the bottom

Put away the removed power module in an antistatic bag or the power module package bag for
future use.
