Attention: When you install an adapter, make sure that the adapter is
correctly seated in the riser-card assembly and that the riser-card assembly is
securely seated in the riser-card connector on the system board before you
turn on the server. An incorrectly seated adapter might cause damage to the
system board, the riser-card assembly, or the adapter.
