Installing a x4–x8 PCI Express bus expander
The x4–x8 PCI Express bus expander is a half-length expansion board. When installed into a x4 PCI
Express expansion slot, the x4–x8 PCI Express bus expander converts the adjacent x4 PCI Express
expansion slot into a x8 PCI Express expansion slot.
The server can support up to two x4–x8 PCI Express bus expander cards. The x4–x8 PCI Express bus
expander can only be installed in expansion slots 5 and 7. Installing the x4–x8 PCI Express bus expander
into expansion slot 5 converts expansion slot 4 to PCI Express x8. Installing the x4–x8 PCI Express bus
expander into expansion slot 7 converts expansion slot 6 to PCI Express x8.
