Expansion cards and expansion card risers
An expansion card in the system 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 not supported or missing. It does not prevent your
system from turning on. However, if F1/F2 pause occurs and an error message is displayed.
Expansion card installation guidelines
The following table describes the supported expansion cards:
Table 42. Expansion card riser congurations
Expansion card riser PCIe slots on the riser Processor connection Height Length Slot width
Full height right riser Slot 2 Processor 1 Full Height Half Length x16
Low prole right riser Slot 2 Processor 1 Low Prole Half Length x16
Low prole left riser Slot 3 Processor 2 Low Prole Half Length x16
Buttery riser Slot 2 Processor 1 Full Height Half Length x16
Buttery riser Slot 3 Processor 1 Low Prole Half Length x8
NOTE: The expansion-card slots are not hot-swappable.
The following table provides guidelines for installing expansion cards to ensure proper cooling and mechanical t. The expansion cards with
the highest priority should be installed rst using the slot priority indicated. All the other expansion cards should be installed in the card
priority and slot priority order.
