3. Backplane

Each drive carrier includes separate LED indicators for drive activity and drive status. Light pipes integrated into the drive carrier direct
light emitted from the LEDs mounted next to each drive connector on the backplane to the drive carrier faceplate, making them
visible from the front of the system.

NOTE: The drive activity LED is driven by signals coming from the drive itself. Drive vendors may choose to operate the activity
LED differently from what is described in the table above. Should the activity LED on a given drive type behave differently than
what is described, customers should take the drive vendor specifications as a reference for the specific drive model to determine
what the expected drive activity LED operation should be.
