The expansion cards with the highest priority should be installed first using the slot priorityindicated. All other expansion cards should be installed in the card priority and slot priority order.NOTE: The x16 link width riser cards on the expansion card riser are cabled to the system board.NOTE: The expansion card slots are not hot swappable.71
