Riser cards for riser connector 1 or 2
If a riser card can be installed on riser connector 1 or 2, the slot numbers of its PCIe slots are
presented in the m/n format in this document.
• The m argument represents the PCIe slot number on connector 1.
• The n argument represents the PCIe slot number on connector 2.
For example, PCIe slot 2/5 represents that a PCIe slot is numbered 2 or 5 when the riser card is
installed on riser connector 1 or riser connector 2, respectively.
RC-2*FHFL-2U-G3
The riser card must be used together with a RC-Mezz-Riser-G3 PCIe riser card.
