Depending on your system conguration, the following PCI Express (PCIe) generation 3 expansion cards are supported:
Table 38. Expansion card riser congurations
Expansion card riser PCIe slots on the riser Processor connection Height Length Slot width
Riser 1A Slot 1 Processor 1 Low Prole Half Length x16
Slot 2 Processor 1 Low Prole Half Length x16
Riser 2A Slot 3 Processor 2 Low Prole Half Length x16
Riser 1B Slot 1 Processor 1 Low Prole Half Length x16
Riser 2B Slot 2 Processor 2 Full Height Three-fourth Length x16
Riser 1B Slot 1 Processor 1 Low Prole Half Length x16
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.
