3 Lock the cable connector to the 3C389 PC Card.
Slide the latching button toward the 3C389 PC Card.
You can leave the latching button retracted, so that if the
cable is yanked, the connector will disconnect from the
PC Card, possibly saving your PC from being pulled off
a table.
4 Insert the 3C389 PC Card in the slot (Figure 2-2).
If you are using a point enabler, note which slot
you use.
The 3C389 PC Card can go in only one way. If you feel
resistance before the 3C389 PC Card is fully inserted,
remove the 3C389 PC Card, turn it over, and reinsert it.
