NOTE: Both the processors must be installed to use riser 1 slots.
Table 22. Guidelines for systems supporting two PCIe expansion cards
Riser PCIe Slot
2 1
3 2
NOTE: Only a three-fourth length card is supported for the PCIe expansion card slot (slot 2) on riser
3.
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 PCIe 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.
