Steps
1. For Riser 1A and Riser 4A, holding the blue touch points, align the holes on the expansion card riser with the guides on the
system board.
2. Lower the expansion card riser into place and press the touch points until the expansion card riser connector is fully seated
on the system board connector.
NOTE: Minimizing angular mating is critical to avoid any damage caused during mating, which can occur at angles larger
than 5° and needs to be assembled vertically and cannot be tilted back and forth.
3. Pull the release tab toward the rear of the chassis to lock the riser.
4. Using a Phillips 2 screwdriver, tighten the blue thumb screw to secure the riser on the chassis.
