Step 12 With one hand holding each side of the module, align the backside of the module to the slot guides in
the vacated slot, and slide the module part way into the slot.
Caution To prevent ESD damage, avoid touching the electronic circuitry and prevent anything else from coming
in contact with the circuitry.
Step 13 With one or both hands on the face of the module, push the module all the way into the slot until it seats

The captive screws should be aligned to their holes in the chassis.
