To remove an expansion card, follow these steps:
1. Unlock the keylock, remove the key, and then turn the keylock to the
access-door release position (see Figure 4-22).
2. Squeeze the dual latches on the expansion-card access door to open the
door, exposing the expansion-card compartment.
3. Record the location of any cables attached to the expansion card you want
to remove, and then disconnect the cables.
