Table 1. Supported configurationsThe table shows the supported configurations
Configurations Expansion card risers PCIe Slots Controlling processor Height Length Slot width
Config 0 N/A 1 Processor 1 Low profile Half length x16
2 PCH Low profile Half length x4
5 Processor 2 Low profile Half length x16
6 Processor 2 Low profile Half length x16
Config 0-1 N/A 1 Processor 1 Low profile Half length x16
2 PCH Low profile Half length x4
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 the other expansion cards should be installed in the card priority and slot priority order.
