If the power ON LED is illuminated and the yellow temperature LED is illuminated: * Leave the power supply on to allow the fan to cool the power supply. * If the internal temperature of the power supply approaches ?30° C (-22° F), the temperature LED may illuminate. Move the power supply to a warmer location.
