    S5520SC:  SC5299 versus SC5650

    leopard

      The Intel documentation says that the following 2 chassis have exactly

      the same dimensions.


           SC5299

           SC5650

       

      The Intel documentation says that the following workstation motherboard


         S5520SC


      has been verified to be compatible with the chassis, SC5650.


      The form factor of S5520SC is SSI EEB (12" X 13").


      I have 2 questions.


      1.  Are the positions of the fasteners (for attaching the motherboard to the chassis) in the

          SC5299 identical to the positions of the fasteners in the SC5650?


      2.  Can I put the S5520SC into the chassis, SC5299?

          1. Ideally yes since both are SSI-EEB compliant

          2. I don't think so due to different power/thermal specification

          • 2. Using S5520SC as a uni-processor board without some power connections.

            The documentation for the S5520SC says that it is a dual-processor motherboard.


            Suppose that I use the board with only 1 low-power processor.  I never use the 2nd CPU slot

            and permanently leave it empty.


            I have 2 questions.


            1.  The motherboard has 4 principal connectors for connecting to the power

                  supply.  The documentation identifies the following 4 connectors.

               

                           J1K3 for main power (24 pins)

                           J9A1 for CPU 1 power (8 pin)
                           J9K1 for CPU 2 power (8 pin)
                           J9K2 for P/S aux/IPMB (5 pin)

             

                Can I leave J9K1 without any connection to the power supply?


            2.  Can I leave J9K2 without any connection to the power supply?

                In other words, can the motherboard still be correctly functional

                     if I leave   J9K2 without any connection to the power supply?
