Power Supplies - Compaq AlphaServer GS60E Installation Manual

The power supplies have two LEDs that indicate normal conditions and faults.
When the system (keyswitch) is off, plugged in, and the circuit breakers are on,
power is present only within the AC box and power supplies. The green VAUX
LEDs on the power supplies should be illuminated. When the system is on, the
VAUX and 48V LEDs should light (see Figure 6-4).
