Hard Disk LED
J16 External Hard Disk Activity LED connector is a 2 x 4-pin connector that allows an
expansion card hard disk drive controller to use the same LED as the onboard IDE
controller. For proper operation, this connector should be wired to the LED output of the
expansion card hard disk drive controller. The LED indicates when data is being read
from, or written to, either the expansion card hard disk drive controller or the onboard
IDE controller (Parallel ATA or Serial ATA).
