Notes
Top PCIe* Slot
CPU #2 – Port DMI 2
(x4 elec, x8 mech)
PCIe* 2.0 Support Only

1U – One PCIe* add-in card slot – PCIe* x16, x16 mechanical
Figure 13. 1U one slot PCIe* riser card (iPC – F1UL16RISER2)
Each riser card assembly has support for a single full height, ½ length PCIe* add-in card. However, riser card
#2 may be limited to ½ length, ½ height add-in cards if either of the two mini-SAS HD connectors on the
server board are used.
Note: Add-in cards that exceed the PCI specification for ½ length PCI add-in cards (167.65mm or 6.6in) may
interfere with other installed devices on the server board.
