LED Support

If your system configuration allows the use of an activity
LED external to the WD Enterprise drive, you can power
the LED from the drive. Pins 10 and 29 are dedicated to
LED support, as shown in Figure 12. To install an external
activity LED, connect the positive lead (anode) of the
LED to pin 29 and the negative lead (cathode) to pin 10.
NOTE: These pins can be used to power an LED located on
the front of the drive, or an external LED in systems
where the front of the drive cannot be seen.
