4.2.2 Replacing a Power Supply
1. Remove the screws located at the corners of the power supply. Place
the screws in a safe place as you will need them later when you install a
new power supply.
2. Use the handle to pull out the defective power supply.
3. Replace it with a 300W power supply.
4. Slide the new power supply in until it clicks into place.
5. Replace the screws you removed in step 1.
6. When you replace a new power supply unit, you should then push the
power supply reset switch to stop the buzzer alarm. The new power supply unit
will link with the other unit immediately and will start working after you press
the power supply reset switch, and the buzzer warning noise will stop.
