December 12th, , PM I made a mistake AsI can see, the blue and the clear cable are inverted. KB has multiple technotes on this issue. As long as you connect same color to same pin number on all modules it will work, but I recomend you to follow correct color code for future troubleshooting: 1- clear, 2 - Blue Color code listed on the DHRIO door. In fact you can delete it now and you will see this string under your path.
