Electrical connections between CPU and PCIe* slots in Intel® Server Board S2600CW2R, S2600CWTR, S2600CW2SR and S2600CWTSR.

  • From PCH: 
  • Slot1: PCIe Gen II x4
  • From the first processor:

    • Slot 5: PCIe Gen III x16 connector.

Electrical x16 for S2600CW2R or S2600CWTR
Electrical x8 for S2600CW2SR or S2600CWTSR

  • Slot 6: PCIe Gen III x16 electrical with x16 physical connector

  • From the second processor:
    • Slot 2: PCIe Gen III x16 electrical with x16 physical connector
    • Slot 3: PCIe Gen III x8 electrical with x8 physical connector
    • Slot 4: PCIe Gen III x16 electrical with x16 physical connector



​Single CPU configuration options are shown in the picture below:

Note Both CPU power connectors need to be connected in order for all the PCIe slots to work even only one CPU is installed.
** PCIe slot 5 could support 75W cards as long as we do not connect another 75W card on PCIe slot 6 and vice versa.



Dual CPU configuration options are shown in the picture below:

Note Standard PCIe slots can provide up to 25W of power. PCIe slot 2, 4, and 6 can provide up to 75W of power. The higher power requirement needs direct power cables from power supplies.

While PCIe slot 5 is also an x16 connector, only 3 x16 PCIe slots on the board can support up to 75W of slot power at a time. This is a configuration limitation based on the System Power budget. When used as riser slot, slot 6 can each provide up to 75W of power to the riser.

** PCIe slot 5 could support 75W cards as long as we do not connect another 75W card on PCIe slot 6 and vice versa.
