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.

Expansion card installation guidelines

Depending on your system configuration, the following PCI Express (PCIe) generation 3 expansion cards are supported:

Table 33. Supported expansion cards

PCIe slot Riser Processor connection Height Length Link width Slot width

1 1 Processor 2 Low Profile Half Length x8 x16

2 1 Processor 2 Low Profile Half Length x8 x16

3 1 Processor 2 Low Profile Half Length x8 x16

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.
