Expansion card installation guidelines

Depending on your system configuration, the following PCI Express (PCIe) generation 3 expansion cards are supported:

Table 1. Supported expansion cardsItem 1 is the PCIe slot 1, on Riser 1 and is connected to Processor 2, it supports a low profile, half length 8x card. The slot width is 16x. Item 2 is the PCIe slot 2, on Riser 1 and is connected to Processor 2, it supports a low profile, half length 8x card. Item 3 is the PCIe slot 3, on Riser 1 and is connected to Processor 2, it supports a low profile, half length 8x card. The slot width is 16x. Item 4 is the PCIe slot 4, on Riser 2 and is connected to Processor 2, it supports a full height, full length 16x card. The slot width is 16x. Item 5 is the PCIe slot 5, on Riser 2 and is connected to Processor 1, it supports a full height, full length 8x card. The slot width is 16x. Item 6 is the PCIe slot 6, on Riser 3 and is connected to Processor 1, it supports a full height, full length 16x card. The slot width is 16x (alternate).
PCIe slot	Riser	Processor connection	Height	Length	Link width	Slot width
1	1	Processor 2	Low Profile	Half Length	x8	x16
2	1	Processor 2	Low Profile	Half Length	x8	x16
3	1	Processor 2	Low Profile	Half Length	x8	x16
4	2	Processor 2	Full Height	Full Length	x16	x16
5	2	Processor 1	Full Height	Full Length	x8	x16
6	3 (default)	Processor 1	Full Height	Full Length	x8	x16
6	3 (alternate)	Processor 1	Full Height	Full Length	x16	x16
7	3 (default)	Processor 1	Full Height	Full Length	x8	x16

NOTE: To use PCIe slots 1 through 4 on the risers 1 and 2, both the processors must be installed.

NOTE: The expansion card slots are not hot-swappable.

The following table provides guidelines for installing expansion cards to ensure proper cooling and mechanical fit. The expansion cards with the highest priority should be installed first using the slot priority indicated. All the other expansion cards should be installed in the card priority and slot priority order.

Table 2. Expansion card installation order The table describes the slot priority for expansion card installation.

1	GPU (double width)	6, 4	2
1	GPU (single width)	6, 4, 7, 5	4
2	RAID H830	7, 6, 4, 5	2
2	RAID H830 (low profile)	3, 2	2
3	100G Intel Omni-Path Architecture Host (OPA) Channel Adapters (HCA)	4, 6	2
	14 Gb InfiniBand, Fourteen Data Rate (FDR) HCA	3, 2, 1	3
