Green and amber lights can alert you to certain conditions.
Light emitting diodes (LEDs) are located either on or near the major serviceable components in the enclosure. When it is lit, the LEDs emit either a green or amber light.
When it is lit, an amber LED indicates a fault or identify condition. If the enclosure or one of the components on your system has an amber LED turned on solid (not blinking) or blinking, identify the problem and take the appropriate action to restore the component to a normal operating condition.
For more information about specific LEDs found on or near the major serviceable components in your enclosure, see Component and attention LEDs.
