*PCIe Generation 2 expansion card.
NOTE: To use PCIe slots 5, 6, and 7, both the processors must be installed.
NOTE: The expansion-card slots are not hot-swappable.
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.
