表格： The Nine LEDs

注释：

The AS-P Ethernet and Status indicators comprise two LEDs (green/yellow and green/red respectively) in one structure. Normally, when one LED is lit, the other is not lit and vice versa, that is, the indicator will show one color at a time.

The LEDs indicate status of AS-P and the ongoing communication.

Status LED

The Status LED on the front of the SmartStruxure devices changes color and flashes to indicate the status of the device.
