Expansion cards and expansion card risers
NOTE: When an expansion card is not supported or missing, riser the iDRAC and Lifecycle Controller logs an event. This
does not prevent your system from booting. However, if a F1/F2 pause occurs with an error message, see Troubleshooting
expansion cards section in the Dell EMC PowerEdge Servers Troubleshooting Guide at www.dell.com/poweredgemanuals.
