Expansion Cards and Expansion-Card Risers
Your system supports up to four PCI Express (PCIe) expansion cards installed
in connectors on an expansion-card riser.
Depending on the configuration, your system may have either riser 1 or
riser 2:
• Expansion-card riser 1 provides three x4 Gen2 PCIe expansion-card slots
and one x8 Gen2 PCIe expansion-card slot.
• Expansion-card riser 2 provides one x4 Gen2 PCIe expansion-card slot and
one x16 Gen2 PCIe expansion-card slot.
CAUTION: Expansion cards can only be installed in the slots on the
expansion-card riser. Do not attempt to install expansion cards directly into
the riser connector on the system board.
Expansion Card Installation Guidelines
• The expansion-card slots support full-height, half-length cards.
• The expansion-card slots are hot-swappable.
• PCI Express Generation 2 expansion cards are supported in all the slots.
