Riser card and PCIe module compatibility

Guidelines
If a processor is faulty or absent, the PCIe slots connected to it are unavailable. For more information
about riser card, PCIe slot, and processor mappings, see
The server provides three PCIe riser connectors on the system board to connect riser cards, which
hold PCIe modules. For more information about the connector locations, see
board components." For information about PCIe slots on a riser card, see riser cards in
You can install a PCIe module in a PCIe slot for a larger-sized PCIe module. For example, an LP
PCIe module can be installed in a slot for an FHFL PCIe module.
A PCIe slot can supply power to the installed PCIe module if the maximum power consumption of the
module does not exceed 75 W. If the maximum power consumption exceeds 75 W, a power cord is
required.
The description for PCIe5.0 x16 (16,8,4) is as follows:

PCIe5.0: Fifth-generation signal speed.

x16: Connector bandwidth.

(16,8,4): Compatible bus bandwidth, including x16, x8, and x4.
For an x8 MCIO connector, x8 indicates the bus bandwidth.
