An expansion card in the computer is a add-on card that can be inserted into an expansion slot on the computer 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 unsupported or missing. It does not prevent your
system from turning on and no BIOS POST message or F1/F2 pause is displayed.
NOTE: The expansion card riser is optional for systems with four hard drives.
