Figure 24. Removing the power supply assembly

7. Make sure that the new power supply assembly is the correct replacement. Some power supply

assemblies automatically sense the voltage or accept universal input, some power supply assemblies
are voltage specific, and some power supply assemblies have a voltage-selection switch. If your power
supply assembly has a voltage-selection switch, make sure that you set the voltage-selection switch
to match the voltage available at your electrical outlet. If necessary, use a ballpoint pen to slide the
voltage-selection switch to the correct position.

• If the voltage supply range in your local country or region is 100–127 V ac, set the voltage-selection

switch to 115 V.

• If the voltage supply range in your local country or region is 200–240 V ac, set the voltage-selection

switch to 230 V.

8. Install the new power supply assembly into the chassis so that the screw holes in the new power supply

assembly are aligned with the corresponding holes in the rear of the chassis. Then, install the three
screws to secure the new power supply assembly in place.

Note: Use only screws provided by Lenovo.
