Power Supply LEDs
Operator interventions typically report all problems related to power supplies. You
can also observe the blinking pattern of LEDs on power supplies to see if they are
functioning correctly.
Power supply LEDs indicate status by the rate at which they blink. The color of
the LED identifies the area of the component being reported.
