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 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
The PowerEdge R7425 system supports up to eight PCI express (PCIe) generation 3 expansion cards, that can be installed on the system
board using expansion card risers. The following table provides detailed information about the expansion card riser specifications:
