NOTE:

Before removing an installed expansion card, disconnect any cables that may be attached

to the expansion card.

a.

If you are installing an expansion card in a vacant socket, you must use a flatblade screwdriver
to pry out the metal shield on the rear panel that covers the expansion slot. Be sure to remove
the appropriate shield for the expansion card you are installing.

b.

If you are removing a PCI or PCI Express x1 card, hold the card at each end and carefully
rock it back and forth until the connectors pull free from the socket. Be sure not to scrape the
card against the other components.
