Backplane
Each drive tray includes separate LED indicators for drive activity and drive status. Light pipes integrated into the drive tray direct
light emitted from LEDs mounted next to each drive connector on the backplane to the drive tray 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 different 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.
