As shown in Figures 1 through 5, LED connectors for individual 
drives are on J7, J8, and J9 for the full size cards, and on J3 for the 
half-size 4-port card. 

Pin 1 is located in the lower left-hand corner of each 10-pin 
connector. The odd-numbered pins, located on the bottom row, are 
3.3V for the anode side of each LED to be connected. The even-
numbered pins are the return or cathode side. 

Table 1 summarizes the LED indicator pin positions for the 
different controllers.
