2. Unplug the power cord from the combined power supply and fan assembly that you are replacing.
3. Unscrew the captive screw on the power supply and fan assembly that you are replacing using the Phillips
screwdriver.
4. Remove the power supply and fan assembly from the chassis by pulling the handle out and away from the chassis.
