Expansion cards and expansion-card risers

NOTE: A missing or an unsupported expansion-card riser logs an SEL event. It does not prevent your system from powering on and no BIOS POST message or F1/F2 pause is displayed.

Expansion card installation guidelines

Depending on your system configuration:

The following PCI Express generation 3 expansion cards are supported:

Table 27. Supported expansion cards

Riser		PCIe slot	Processor	Height	Length	Link width	Slot width
			connection
1		1	Processor 2	Low Profile	Half Length	x8	x16
1		2	Processor 2	Low Profile	Half Length	x8	x16
1		3	Processor 2	Low Profile	Half Length	x8	x16
2		4	Processor 2	Full Height	Full Length	x16	x16
2		5	Processor 1	Full Height	Full Length	x8	x16
3	(default)	6	Processor 1	Full Height	Full Length	x8	x16
3	(alternate)	6	Processor 1	Full Height	Full Length	x16	x16
3	(default)	7	Processor 1	Full Height	Full Length	x8	x16

NOTE: To use PCIe slots 1 through 4 on the riser, 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. Install all other expansion cards in card priority and slot priority order.

Table 28. Expansion card installation order

Card priority	Card type			Slot priority	Max allowed
1	PCIe Bridge			4	1
2	10		Gb NICs (full height)	4,6,5	3
	10		Gb NICs (low profile)	2,3,1	3
3	1	Gb NICs (full height)		4,6,5	3
	1	Gb NICs (low profile)		2,3,1	1
4	Integrated RAID			integrated slot	1
5	NDC			integrated slot	3
