Attention: Use of the lower corner support retainer might interfere with the docking of
the PCI card when positioned within the system. Ensure the retainer does not interfere with
the adapter connectors on the system backplane.

the presence of a connector will not allow the adapter edge to be seated into the retainer
groove, ensure the retainer is still locked firmly against that edge or connector.
