Step 1. Align the riser with the I/O tray, making sure that the sides of the riser fit into the guides on the I/O
tray, and insert the riser; then, press the riser into the I/O tray until the connector is fully seated.
Step 2. Tighten the captive screw (item 4 in preceding figure) that secures the riser to the I/O tray board.

in the chassis. See "Install the I/O tray" on page 335.
