Expansion cards and expansion card riser
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 unsupported or missing. It does not prevent
your system from turning on and no BIOS POST message or F1/F2 pause is displayed.
Expansion card installation guidelines
Your system supports Generation 1, Generation 2, and Generation 3 cards. The following table provides riser configurations for
R430 systems:
NOTE: Full-height: 312mm, Half-height: 175.26mm, Low-profile: 119.91mm.

NOTE: The PCIE_G3_X8 and PCIE_G3_X16 are the two different types of risers supported on R430 systems. You can
install an expansion card on the system board only using expansion-card riser.
NOTE: The expansion cards 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.
