1. on a model 6c3, open the front and rear rack doors and place the system into the service position as described in “placing the model 6c3 into the service position” on page 53.
on a model 6e3, open the bezel door.
2. shut down the system as described in “stopping the system” on page 51.

5. refer to the pci adapter placement reference for information regarding slot restrictions for adapters that can be used in this system.
6. if necessary, remove the adapter expansion slot shield.
7. before handling any card, board, or memory dimm, be sure to use your electrostatic discharge strap to minimize static-electric discharge. refer to “handling static-sensitive devices” on page 50.
8. if necessary, remove the adapter from the antistatic package.
avoid touching the components and gold-edge connectors on the adapter.
9. place the adapter, component-side up, on a flat, static-protective surface.

11. carefully grasp the adapter by its top edge, and align the adapter with the expansion slot and its connector on the pci riser card.
12. press the adapter firmly into its connector.
when you install an adapter into the system, be sure that it is completely and correctly seated in its connector.
