Expansion cards and expansion card riser
An expansion card in the server is an add-on card that can be inserted into an expansion slot on the
system board or riser card to add enhanced functionality to the system through the expansion bus.
NOTE: A System Event Log (SEL) event is logged if an expansion card riser is unsupported or
missing. It does not prevent your system from turning on and no BIOS POST message or F1/F2
pause is displayed.

4 2 Processor 2 Full Height Full Length x16 x16
5 2 Processor 1 Full Height Full Length x8 x16
6 3 (alternate) Processor 1 Full Height Full Length x16 x16
NOTE: To use PCIe slots 1 through 4 on the risers 1 and 2, both the processors must be installed.
NOTE: The expansion card slots are not hot-swappable.
The following table provides guidelines for installing expansion cards to ensure proper cooling and
mechanical fit. The expansion cards with the highest priority should be installed first using the slot priority
indicated. All the other expansion cards should be installed in the card priority and slot priority order.
NOTE: Ensure that the 100 G OPA x16 card is installed in slot 6 (x16 PCIe) on the alternate riser 3.
