If you are replacing a server component in the server, you need to slide the server out from the rack
enclosure, turn off the server and peripheral devices, and disconnect the power cords and all external cables.
To replace the PCI riser-card assembly, complete the following steps.
Step 1. Install the adapter in the PCI riser-card assembly (see "Replacing an adapter" on page 185 or

Step 2. Reconnect any adapter cables that you disconnected when you removed the PCI riser-card
assembly.

PCI riser-card connector on the system board; then, place your thumbs on locations marked by the
blue tabs and press down on the PCI riser-card assembly. Make sure that the riser-card assembly
is fully seated in the connector on the system board.
