Expansion Card Installation Guidelines

Your system supports third Generation 10 PCIe expansion card slots that include one dedicated slot for PERC 9 storage card and one dedicated riser-slot for Network Daughter Card (NDC).

Slot 1 connector functions as an x8 connector and can be extended as two x4 slots when the left I/O riser is installed.

Slot 9 connector functions as an x16 connector and can be extended as two x8 slots when the right I/O riser is installed.

NOTE:Left and right optional risers supports Generation 2 expansion cards. Generation 3 expansion cards will be supported in future.
Table 1. Supported Expansion CardsThe following table shows supported expansion card in R920 system.
Riser PCIe Slot Processor Connection Height Length Link Width Slot Width
1 Processor 1 Full Height Half Length x8 x24
1 (NDC riser) 2 Processor 1 Full Height Half Length x8 x16 - reversed
2 (optional)
NOTE:If installed as a left I/O riser
1/1 Full Height Full Length x4 x8
2/2 Full Height Half Length x4 x8
3 Processor 1 Full Height Half Length x8 x16
4 Processor 2 Full Height Half Length x16 x16
5 Processor 2 Full Height Half Length x16 x16
6 Processor 3 Full Height Half Length x16 x16
7 Processor 3 Full Height Half Length x16 x16
8 Processor 4 Full Height Half Length x16 x16
9 Processor 4 Full Height Half Length x16 x24
3 (optional)
NOTE:If installed as a right I/O riser
1/9 Full Height Full Length x8 x16
2/10 Full Height Half Length x8 x16
NOTE: Do not install a full-height expansion card on PCIe slot 10.
NOTE:The expansion cards are not hot-swappable. Ensure the AC power supply is completely removed before installing the expansion cards.

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.
