NOTE: Only a three-fourth length GPU card is supported for the PCIe expansion card slot (slot 2) on riser 3.
CAUTION: If the 10 GbE network daughter card is installed, you cannot install the GPU card.
NOTE: You can install expansion cards only on one slot on riser 2.
NOTE: Both the processors must be installed to use the x16 link on the riser 2 slot.
The following table provides a guide for installing expansion cards to ensure proper cooling and mechanical fit. The
expansion cards with the highest priority must be installed first using the slot priority indicated. All other expansion
cards must be installed in card priority and slot priority order.
