direct light emitted from the LEDs mounted next to each drive connector on the backplane to the drive tray faceplate, making them

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 driver vendor specifications as a reference for the specific drive model to determine
what the expected drive activity LED operation should be.
