10. PCI Riser Card Support

The system includes two riser card slots on the server board. Available riser cards can be used in either slot.

This section will provide an overview of each available riser card and describe the server board features and

architecture supporting them.

10.1 Riser Slot Overview

The server board includes two riser card slots labeled “RISER 1” and “RISER 2”. The following diagram

illustrates the general server board architecture supporting these two slots.

Figure 47. Riser Slot Architecture

Riser slot-1 includes a total of 24 PCIe Gen3 bus lanes; 16 routed from CPU-1 and 8 routed from CPU-2.

Riser slot-2 has 24 PCIe Gen3 bus lanes routed from CPU-2. Each riser slot is capable of supporting several

different types of multi-slot riser cards. In order to support the maximum number of add-in cards, both CPU-1

and CPU-2 must be populated. With only CPU-1 installed, riser slot-2 has no functionality and depending on

the riser card installed, riser slot-1 will be limited to supporting a single x16 PCIe add-in card or two x8 PCIe

add-in cards. See

Figure 48. Intel

Server Board S2600GZ/GL PCI Bus Layout Diagram, to determine PCI

bus lane routing for each riser card.

NOTE: The riser card slots on the server board are designed to support riser cards only. Inserting a

PCIe add-in card directly into the riser card slot on the server board will result in damage to the server board,

the add-in card, or both. PCIe add-in cards should only be installed into a supported riser card assembly.
