Backplane and Server Board Overview
Each drive tray includes two 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 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.
