Removing a PCI Card

1Follow the procedures in "Before You Begin" on page 53.

2Gently push the release tab on the card retention door from the inside to pivot the door open. Because the door is captive, it will remain in the open position.

3If you are removing the card permanently, install a filler bracket in the empty card-slot opening. If you need a filler bracket, contact Dell (see page 116).

NOTICE: To connect a network cable, first plug the cable into the network device and then plug it into the computer.
