The server supports up to eight PCIe slots. Five slots are on the system board and three are through a
riser card. The riser card is standard on some models as shown in the table below. It is optional on all
other models. The use of slots 1 - 5 require processor 2 to be installed. The slot specifics are as follows:
Slot 1: PCIe 3.0 x8 (x16 mechanical): Full-height, half-length (optional with riser card, requires
processor 2)
Slot 2: PCIe 3.0 x8 (x16 mechanical): Full-height, half-length (optional with riser card, requires
processor 2)
Slot 3: PCIe 3.0 x8 (x16 mechanical): Full-height, half-length (optional with riser card, requires
processor 2)
Slot 4: PCIe 3.0 x8: Low profile, half-length (requires processor 2)
Slot 5: PCIe 3.0 x8: Low profile, half-length (requires processor 2)
Slot 6: PCIe 3.0 x8: Low profile, half-length
Slot 7: PCIe 3.0 x8: Low profile, half-length
Slot 8: PCIe 3.0 x8: Low profile, half-length
The following table lists the ordering information for the riser card.
