4.Connect the drive activity remote LED (optional)

This drive provides connections for a remote drive activity LED. This step is optional because the drive will work fine without an LED connected, but many people find this to be helpful to determine when the drive is actively reading or writing data.

Most host systems provide this LED which is a small “bulb” (actually a light-emitting diode) located on the host’s front panel. Simply locate this LED and connect the attached pair of wires to the pins on the drive as shown in Figure 6 below.

The shaded pins are shipped with a cover installed. Do not install jumpers on these pins. Retain the cover unless you install a 20-pin plug.

Note: On some LEDs the flat side of indicator is cathode.
