Configuring Riser Card PCIe Expansion Slots

The riser card RSC-H2-6888G4L features two PCIe slots that require a PCIe cable connection
for those slots to be enabled. Riser card slot 1 (system slot 5) can support either a PCIe
x16 or PCIe x8 cable connection and riser card slot 2 (system slot 6) can support a PCIe x8
cable connection. Riser card slots 3 and 4 (system slot 7 and 8) are connected directly to
the riser card's PCB gold fingers. For SYS-620H-TN12R, there are two PCIe x8 connectors
on the X12DHM-6 motherboard, JPCIE2A1 and JPCIE2B1, that are allocated to provide the
PCIe cable connections to RSC-H2-6888G4L. Below is the table for the supported riser card
PCIe slot configurations.
