Note: In this position, the locking bar locks the handle in the down position and prevents it from
being pulled up while the PCI adapter cassette is being removed.
3. Examine the PCI adapter slot opening carefully, and note the location of the dovetail rails and the
cassette guide rails. A flashlight can be used to enable you to see the dovetail rails and the cassette
guide rail slots, as shown in the following illustration.
1 Cassette Left Dovetail Rail
2 Cassette Right Dovetail Rail

4. Hold the PCI adapter cassette at the PCI adapter slot so that the PCI adapter cassette is
perpendicular to the slot and level with the slot opening.
5. Align the bottom edge of the PCI cassette cover with the PCI cassette guide rail on the system board
or I/O unit.
6. Slide the cassette partially into the guide.
Attention: If the cassette does not slide in smoothly, the cover might not have engaged the PCI
cassette guide rail. Carefully pull the adapter back out and start again.
7. As you slide the cassette into the slot, ensure that the dovetail rail on the top of the PCI adapter
cassette aligns with the mating slots on any cassettes that might be installed on the left and right
sides.
8. Push the cassette in until it is flush with any other installed cassettes.
