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.

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.
