PowerEdge R415 Technical Guide
11.5 LED Indicators
Each disk drive carrier has two LED indicators visible from the front of the system. One is a green LED for
disk activity and the other is a bicolor (green/amber) LED for status information. The activity LED is driven
by the disk drive during normal operation. The bicolor LED is controlled by the SEP device on the backplane.
Both LEDs are used to indicate certain conditions under direction of a storage controller.
