Expansion Card Installation Guidelines
Your system supports two PCIe Generation 2 expansion cards installed on two
expansion-card risers.
• Riser1: Supports PCIE_G2_x16 full-height half-length expansion card.
• Riser2: Supports PCIE_G2_x8 full-height half-length expansion card.
• The expansion-card slot is not hot-swappable.
• PCI Express Generation 1 and Generation 2 expansion cards are supported
in the slot.
CAUTION: To ensure proper cooling, only one of the two expansion cards can
have a power consumption of greater than 15 W (up to 25 W maximum), not
including the integrated storage controller.
• Table 3-1 provides a guide 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 other
expansion cards should be installed in card priority and slot priority order.
