Expansion card installation guidelines

Your system supports PCI Express Generation 3 expansion cards.

Table 1. Guidelines for systems supporting three PCIe expansion cardsThis table describes guidelines for 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.

Table 2. Guidelines for systems supporting two PCIe expansion cardsThis table describes the guidelines for systems supporting two PCIe expansion cards.
Riser	PCIe Slot	Processor Connection	Height	Length	Link Width	Slot Width
2	1	Processor 1	Low Profile	Half Length	x8	x16
2	1	Processor 2	Low Profile	Half Length	x16	x16
3	2	Processor 1	Full height	Three-fourth Length	x16	x16

NOTE Only a three-fourth length card is supported for the PCIe expansion card slot (slot 2) on riser 3 when no mini-PERC card is installed. Supported length with mini-PERC card installed is half length.

NOTE For a system with three PCIe cards, only MiniSAS HD third-party cards are supported in slot 3. For a system 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. Install the expansion card by following the card priority and slot priority order as shown in the table.

Table 3. Expansion card installation priorityThis table describes the guidelines to install expansion cards.
Card Priority	Card Type	Systems Supporting up to 2 PCIe Expansion Cards		Systems Supporting up to 3 PCIe Expansion Cards
Card Priority	Card Type	Slot Priority	Max Allowed	Slot Priority	Max Allowed
1	PCIe Bridge	N/A	N/A	1	1
2	RAID	1	1	3, 1	2
3	100 G HCA/OPA HFI	1	1	3, 2 (3, 1 for CX4/OPA)	2
4	40 G NICs	2, 1	2	3, 2	2
5	FC16 HBA	2, 1	2	3, 2, 1	3
6	10 Gb NICs	2, 1	2	3, 2, 1	3
7	FC8 HBA	2, 1	2	3, 2, 1	3
8	1 Gb NICs	2, 1	2	3, 2, 1	3
9	Non-RAID 12 Gb SAS	1	1	3, 1	2
10	Integrated RAID	Integrated Slot	1	Integrated Slot	1
11	NDC	Integrated Slot	1	Integrated Slot	1
12	NVMe PCIe SSD	1,2	2	3, 2, 1	2

NOTE To support x16 PCIe link width, the 100 G HCA/OPA HFI in slot 1 needs processor 2 and x16 center_riser2.
