1. Wear an electrostatic discharge (ESD) strap around your bare wrist and connect the strap to
an ESD point on the chassis. See ESD Prevention.
2. Take IOM out from its antistatic bag.
3. Identify the slot of IOM.
4. If the slot is covered with a blank plate, loose its screws with a cross screwdriver and
remove the plate, see Replacing an Expansion Module.
5. Position the IOM so that its front side faces you. Make sure that the lever is on the left side
and the IOM module is plain with the outside edge of the expansion slot. Rotate the levers
to outside, and slide the expansion module straight into the slot along the guide rail.
6. When the lever head is inserted into the expansion slot, you should rotate the levers to the
front of the module and slide the IOM into the slot until you feel resistant.
7. Tighten the screws on the IOM with a cross screwdriver.
