Chapter 2 Controls, Indicators, and Ports Power Supply Indicators Each of the HP NetServer LXr Pro8's power supplies has these indicators: DC Output Indicator AC Input Indicator Attention Indicator Figure 2-2. Power Supply LEDs Table 2-2. Power Supply LEDs Control DC Output Indicator AC Input Indicator Attention Indicator Description Green indicates that DC power is online. During normal operation, this LED should always be green. Green indicates that the power supply is receiving AC power. This LED is green whenever the server is connected to AC power. Amber indicates that one or more DC output voltages are out of specification. It does not always indicate a problem: the LED is normally lit when the system is plugged in but not running. But if the LED lights during system operation, the power supply could have a problem. 7
