Riser cards
To expand the server with PCIe modules, install riser cards on the PCIe riser connectors.
Riser card guidelines
Each PCIe slot in a riser card can supply a maximum of 75 W of power to the PCIe module. You must
connect a separate power cord to the PCIe module if it requires more than 75 W of power.
If a processor is faulty or absent, the PCIe slots connected to it are unavailable.
The slot number of a PCIe slot varies by the PCIe riser connector that holds the riser card. For
example, slot 1/4 represents PCIe slot 1 if the riser card is installed on connector 1 and represents
