Replacement:
1. Position the HSC Expansion I/O exchange PCB, component side up, over the alignment pins (see Fig-
ure 7-19).

PCB stops against the alignment pins.
3. Insert and tighten the two Phillips head screws, taking care to not strip the screw standoffs.
4. Align the expansion I/O card in the appropriate slot.
5. Insert the expansion I/O card into the chassis until it contacts the system card and the extractor levers
engage the chassis tabs.
6. Push extractor levers down to fully seat the expansion I/O card into the system card. The levers should
be parallel with the rear bezels.
