Expansion Cards And Expansion Card Riser; Expansion Card Installation Guidelines - Dell Storage NX3330 Owner's Manual

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 28. Systems supporting three PCIe expansion cards

3 3
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.
