Expansion cards and expansion card riser
An expansion card in the server 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 PCI Express Generation 3 expansion cards.
Table 24. Systems supporting three PCIe expansion cards
Riser PCIe Slot Processor Connection Height Length Link Width Slot Width
1 1 Processor 2 Low Profile Half Length x16 x16
1 2 Processor 2 Low Profile Half Length x8 x16
3 3 Processor 1 Low Profile Half Length x16 x16
NOTE: Both the processors must be installed to use riser 1 slots.
NOTE: For a server with three PCIe cards, only MiniSAS HD third party cards are supported in slot 3. For a server with two
PCIe cards, only MiniSAS HD third-party cards are supported in slot 1.
NOTE: You can install expansion cards only on one slot on riser 2.
NOTE: Both the processors must be installed to use the x16 link on the riser 2 slot.
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 the specified card priority and slot priority order.
NOTE:
Use the "Systems Support up to 3 PCIe Expansion Cards" column for installation on the Dell Storage NX3330
system.
