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.
Step 6. Install the PCI riser-card assembly in the server (see "Replacing a PCI riser-card assembly" on
