5. Pivot the power supply assembly as shown and then lift the power supply
assembly to remove it from the chassis.
6. Make sure that the new power supply assembly is the correct replacement.
Some power supply assemblies automatically sense the voltage, 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.
v If the voltage supply range in your local country or region is 100–127 V ac,
set the voltage-selection switch to 115 V.
