Enclosure LED Status Indicators
If you use an enclosure that has an integrated AMCC/3ware CCU (chassis control unit), the LEDs on your enclosure also provide some status information. The chassis should come with a cable which attaches to the I2C port on the controller.

| Note: The following table is an example only. Check with your chassis documentation for more details. Not all features may be supported or implemented in the same way.
