Power Supply
The power supply is auto-switching capable. This feature enables it to automatically sense
the input voltage and operate at a 100-120v or 180-240v. An amber light is illuminated on
the power supply when the power is switched off. An illuminated green light indicates that
the power supply is operating.
Changing the Power Supply
1. Remove power from the system as described in section 3.1, and remove the left chassis
cover.
2. Disconnect the cables from the motherboard to the power supply.
3. Remove the screws securing the power supply to the chassis, which are located on the
rear of the chassis. Save the screws for later use.
4. Lift the power supply out of the chassis.
5. Replace the failed power supply with an identical power supply model.
6. Secure the new power supply using the screws previously saved.
7. Plug the AC power cord back into the module and power-up the system.
