The general operation of non-port-side LEDs during normal operation (no faults) is as follows:
• The two power supply status LEDs display steady green when the power supply is receiving and
transmitting power. The top LED indicates status of input voltage, which is AC for an AC power
supply or DC for a DC power supply. The bottom LED indicates status of DC output voltage.
• The fan status LED displays amber when the device is first powered on until POST completes.
