expansion card.
✎
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, remove the appropriate
expansion slot cover on the back of the chassis. Pull the slot cover straight up from the
socket then away from the inside of the chassis.
b. If removing a standard PCI expansion 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 1 then away from the inside of the chassis 2 to release it
from the chassis frame. Be sure not to scrape the card against the other components.
