Power supply

  1. Lift the power supply out of the chassis.
  2. If the power supply has a voltage-selection switch, ensure that it is set to match the voltage available at the electrical outlet.
  • If the voltage supply range in your local country or region is 100-127 V ac, set the switch to 115 V.
  • If the voltage supply range in your local country or region is 200-240 V ac, set the switch to 230 V.
  1. Install the new power supply and install the three screws that secure the power supply at the rear of the chassis and install the screw that secures the power supply at the front.
  2. Position the system board so that the screws holes are properly aligned and install the system board screws.
  3. Route the power supply cable through the cable clamps underneath the hard disk drive and reconnect all power supply cables to the system board.
  4. Install the hard disk drive. See "Replacing the hard disk drive".
  5. Align the drive bay assembly studs with the two slots on the sides of the chassis and place it into position. Reconnect any diskette drive and optical drive cables that were disconnected.
  6. Using the blue handle, slide the drive bay assembly towards the rear of the chassis until it snaps into position.
  7. Reinstall the front bezel.
  8. Go to "Completing the parts replacement".
