Disk Carrier LED Indicators
The LED on the physical disk carrier indicates the state of each physical disk. Each disk carrier in your enclosure has
two LEDs: an activity LED (green) and a status LED (bicolor, green/amber). The activity LED is active whenever a disk is
being accessed while the status LED indicates when a disk is being spun up, is rebuilding, or is in a fault state.
