Power Supply LEDs

The power supply has three LEDs; two green LEDs (ac power good and dc power good), and one amber
LED, which indicate the power supply status. If both of the green LEDs are on solid (not blinking) and the
amber LED is off, then the power supply is operating correctly. If the ac power good LED is on, the dc
power good LED is blinking, and the amber LED is off, then the system is turned off, but the power supply
is still connected to the power source. If the amber LED is active, then the power supply is not operating
correctly.
