Each drive on a control expansion or expansion enclosure has two light-emitting diode (LED) indicators; they have no controls or connectors.
The drive indicator LEDs on all systems use the same color and flashing patterns for both sizes of drives.
LED indicators on a vertical 2.5 in. (6.35 cm) drive shows the location of the LEDs on a small form factor (SFF) 2.5-inch drive.

LED indicators on a horizontal 3.5 in. (8.89 cm) drive shows the location of the LEDs on a
3.5-inch drive.
