Expansion cards
The expansion card in the system is a printed circuit board that can be inserted into an expansion slot on the system board riser card to add
functionality to the system through the expansion bus.
NOTE
: A missing or an unsupported expansion card riser logs an System Event Log (SEL) event. This does not prevent your
system from powering on and no BIOS, POST messages or F1 or F2 pause is displayed.
