9. 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.
9.1 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 31. 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. Riser cards for each riser slot are identical. 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.
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.
