2.6.2 Installing an expansion card to the right PCIe riser
card bracket
The pre-installed right PCIe riser card bracket on the PCIE2 slot has three PCIe x16 slots,
two PCIe x16 slots and one PCIe x8 slot. The two PCIe x16 slots provides x16 Gen4 links,
with the top PCIe slot’s signal provided from CPU1 and the bottom PCIe slot’s signal coming
from CPU2. The PCIe x8 slot is reserved only for a PIKE II card.
To install PCIe x16 (Gen4 x16 link) proprietary cards, such as a graphics card to the right
PCIe riser card bracket:
1. Remove the screw from the PSU air duct, then lift and remove the PSU air duct from
the chassis.
2. Loosen the two (2) thumbscrews (A) securing the right PCIe riser card bracket to the
chassis, then lift the right PCIe riser card bracket upwards (B) out of the chassis to
detach it from the PCIe x16 slot on the motherboard.
