The locations of the PCIe slots are shown in the following figure.
Figure 8. Slot locations
Riser 1 supplies slots 1, 2, and 3, and Riser 2 supplies slots 5 and 6. The slots that are available for use
depend on the number of riser cards that are installed and whether the second processor is installed, as
shown in the following table.
