See Figure 32.
1. Remove the I/O riser board from its antistatic protective wrapper.
2. Holding the board by the top edge or upper corners, carefully insert the edge connector of the
board into the connector on the PHP I/O carrier. Press the board firmly into the connector
until it is fully seated.
3. Insert the screw you removed earlier in the threaded hole in the chassis (B in Figure 32).
Tighten the screw firmly (8.0 inch-pounds).
