Expansion cards and expansion card risers
An expansion card in the system is an add-on card that can be inserted into an expansion slot on the system board or a slot on a riser card
to add enhanced functionality to the
system through the expansion bus.
NOTE: A System Event Log (SEL) event is logged if an expansion card riser is not supported or missing. It does not prevent your
system from turning on. However, if F1/F2 pause occurs and an error message is displayed.
Expansion card installation guidelines
Depending on your system conguration, the following PCI Express (PCIe) generation 3 expansion cards are supported:
