Expansion Card Installation Guidelines

Depending on your system configuration:
  • PowerEdge R720 supports seven expansion cards
  • PowerEdge R720xd supports six expansion cards

The following PCI Express Generation 3 expansion cards are supported:

Table 1. Supported Expansion Cards
Riser PCIe Slot Processor Connection Height Length Link Width Slot Width
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 Standard Height Full Length x16 x16
2 5 Processor 1 Standard Height Full Length x8 x16
3 (default) 6 Processor 1 Standard Height Full Length x8 x16
3 (default) 7 Processor 1 Standard Height Full Length x8 x16
3 (alternate) 6 Processor 1 Standard Height Full Length x16 x16
  • NOTE: To use PCIe slots 1 through 4 on the riser, both the processors must be installed.
  • NOTE: PowerEdge R720xd does not support riser 3 (default).
  • 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. All other expansion cards should be installed in card priority and slot priority order.
