Compaq AlphaServer GS60E Service Manual page 33

Six status indicator LEDs (see Figure 2-1) show the state of the system. Table
2-1 describes the conditions indicated by the lights.
NOTE: With the keyswitch in the On position, if all six LEDs are blinking, one
or more of the power supplies has failed or there is a missing power
supply. With the keyswitch in the Off position, the LEDs will also blink
but do not provide power supply status.
