Expansion Cards and Expansion-Card Risers

The system supports up to four PCI Express (PCIe) expansion cards on two

expansion-card risers.

• Expansion-card riser 1 provides two

PCIe x4-link Gen 2 expansion slots.

• Expansion-card riser 2 is offered in two versions:

– The standard expansion-card riser 2 provides two

PCIe x8-link Gen 2

expansion slots.

– The optional expansion-card riser 2 provides one PCIe x16-link

Gen 2

expansion slot.

CAUTION: Expansion cards can only be plugged into the slots on the expansion-

card risers. Do not plug any expansion cards into the riser connectors on the

system board.

To identify expansion slots, see "Expansion-Card Riser-Board Components

and PCIe Buses."

Expansion Card Installation Guidelines

Observe the following notes and guidelines regarding the expansion-card

slots:

• PCI Express Generation 2 and Generation 1 expansion cards are supported

in all slots.

• In slots 2, 3, and 4, expansion cards can have a maximum length of

24.13

cm (9.5-inch). Slot 1 supports a full-length (30.99-cm [12.2-inch])

expansion card.

• The system supports three full-height expansion cards and one low-profile

expansion card (slot 2).

• Although slots 1 and 2 are physically PCIe x8 connectors, they function

only as PCIe x4-link slots.
