9.4.2 1-Slot PCIe x16 Riser Card (option)
Using this riser card, x16 PCIe bus lanes are routed to Riser Slot #2 from CPU #2. This riser card option can
only be used in a dual processor configuration. This riser card option has no functionality in a single processor
configuration.
9.4.3 2-Slot Butterfly Riser Card (option)
This riser card option provides support for up to two add-in cards.
The riser card assembly (card + bracket) is designed specifically to support an Intel
®
Integrated RAID Module
in the x8 PCIe slot on the back side of the riser. Other PCIe add-in cards cannot be supported in this add-in
card slot.
By default, x8 PCIe bus lanes are routed from CPU#1 to support this add-in card slot. However, should the
system be configured with a an 8-port Intel
®
C600 Upgrade Key, four of the eight PCIe bus lanes from CPU #1
will be routed via a multiplexor to the Intel
®
C602 chipset to support the embedded 8-port SCU SATA/SAS
controller.

Note: When this riser option is configured with an Intel
®
Integrated RAID Module, some PCIe add-in cards
(those with heat sinks attached) installed in Riser #1 were found to interfere with the RAID module. Properly
installed add-in cards should have no contact between them. Intel does NOT recommend operating a server
system when contact is observed between add-in cards.
