6.4.1 PCI Express* Connectors

The Intel ® Server Board S2600KPR uses three PCI Express* slots physically with different
pin-out definition. Each riser slot has dedicated usage and cannot be used for normal PCIe
based add-in card.
Riser slot 1: Provide PCIe x16 to Riser. (Using standard 164-pin connector)

Riser slot 2: Provide PCIe x24 to Riser, or x8 to Intel

pin HSEC8 Connector)
Riser slot 3: Provide PCIe x24 to Riser. (Using 200-pin HSEC8 Connector)

