Table 3-9	Expansion card slot description and compatibility
Slot	Type		Mechanical compatibility	Electrical compatibility
1	PCIe3 x8 (4) — CPU0		x8	x4
2	PCIe3 x16	— CPU0	x16	x16
3	PCIe3 x16	(8) — CPU1	x16	x8
4	PCIe3 x16	— CPU1	x16	x16
5	PCIe2 x8 (4) — CPU0		x8	x4
6	PCIe3 x16	— CPU0	x16	x16
7	PCI 32/33 — CPU0		PCI	PCI

NOTE: The PCIe designators indicate the mechanical connector size and number of electrical PCIe lanes routed to an expansion slot. For example, x16(8) means that the expansion slot is mechanically a x16 length connector, with 8 PCIe lanes supported.

NOTE: Slots one and five use open-ended PCIe connectors, so a PCIe x16 card can inserted. This allows the workstation to support more PCIe x16 expansion cards. A x16 card typically trains and runs at the maximum lane width available by the expansion slot. The card runs at the reduced lane width, with a corresponding performance decrease.

NOTE: A eighth slot opening in the chassis has no corresponding expansion connector on the system board. This slot opening is provided for devices that do not require system board card plug-in capability.

NOTE: It is normal for the expansion card retention clamp to have a slight (5-10 degree) angle when closed. If the angle is greater than this, open the clamp and ensure that all cards are properly seated and all the brackets are mated to the chassis, then re-close the clamp.
