5. Before installing an expansion card, remove the expansion slot cover or the existing expansion
card.
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 remove the metal slot
cover on the rear panel that covers the expansion slot. Be sure to remove the appropriate
slot cover for the expansion card you are installing.
b. If you are removing a standard PCI card, hold the card at each end, and carefully rock it
back and forth until the connectors pull free from the socket. Pull the expansion card
straight up from the socket then away from the inside of the chassis to release it from the
chassis frame. Be sure not to scrape the card against the other components.
