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.
The VxRail D Series appliance supports PCI express (PCIe) generation 3 expansion cards that can be installed on the system
board using expansion card risers. This system supports low profile (LP) and full height (FH) X1 expansion card risers.
NOTE:
To avoid data loss, ensure that you refer to the procedures in SolVe Online for VxRail or the SolVe Desktop
application before performing any memory or expansion card replacement or upgrade procedures.
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 and no BIOS POST message or F1/F2 pause is displayed.
The following tables provide detailed information about the expansion card riser specifications:

Expansion card installation guidelines
The following table describes the supported expansion cards:

Expansion card riser
Full height right riser 1 (1 CPU systems)
Low profile right riser 1 (2 CPU systems)
Low profile left riser 2 (2 CPU systems)
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.
