Riser Card Support

The server board provides three riser card slots identified as: Riser Slot #1, Riser Slot #2, and Riser Slot #3.
Note: The riser card slots are specifically designed to support riser cards only. Attempting to install a
PCIe* add-in card directly into a riser card slot on the server board may damage the server board, the add-in
card, or both.
The PCIe* bus interface for each riser card slot is supported by each of the two installed processors. The
following tables provide the PCIe* bus routing for all supported risers cards.
Note: A dual processor configuration is required when using Riser Slot #2 and Riser Slot #3, as well as the
bottom add-in card slot for 2U riser cards installed in Riser Slot #1.
